Malaysia Bid Round 2023 (MBR 2023)

Tool: ArcGIS Pro 2.6.3 Technique: Symbolization, labeling and SQL expression

MBR 2023 is a peak event that culminates all the effort of data collection and stock take of hydrocarbon resource in the Malaysia. It is an annual event that put together all the exploration blocks, discoverable hydrocarbon fields and late life assets for upstream sectors to evaluate and invest in.

Leading up to the event, the Malaysia Petroleum Management (MPM) updates, re-evaluate and produces maps; static and digital, to cater to the need for the most update stock-take of information that can be gained from various source of exploration output; seismic, full tensor gradiometry, assets; cables, pipelines, platforms, as well as discoverable resources. This year's them aims to include various prospects and initiative to align the industry itself with lower carbon emission and to explore the option for carbon capture storage (CCS) attempts in the popular basins such as the Malay and Penyu Basin. This is a big follow-up with the closing of MBR 2022 with the PSC signing for 9 blocks a few days earlier.

Over ~70 maps for unique blocks have been produced during the finalization stage, ~210 maps during data evaluation and additional 20 for the event. And this excludes the standardized maps to formalize information requested by prospective bidders as well as clients who are facing prospects of extending their contract.

The standardization of the map requires the optimization of workflow and standard templates to cater to rapid changes and exporting to rapid output.

The devil in the details

I have started to post some videos demonstrating some tools in ArcGIS Pro. Short ones and pretty quick ones which I strived for since I absolutely am frightened with the idea of irritating people with unnecessary voice-over. It has no garnered much response and it's cool with me. Although, the lack of traction does things to my insides, I go back to the real reason I am doing thing, which is to stash the tools that I managed to learn on my own by trials and errors and keep them somewhere I can refer back to it to remember how it works.

Creating maps involves a number of iterative processes made to suit the intended output. Although creating maps itself is a form of art; heavily reliant on target audience's knowledge and aesthetical preference, it is still an inherently democratic science. Thus, knowing the mainstream technology and tools in the industry to express your vision or message is given. So for those just starting out with using geographical information software (GIS) for your final year project or research, this videos are meant for you. The purpose is not to overwhelm you with too many information, or distract you with my narration, but to follow in real-time the process from the start up of the software to the running of tools that generates the information needed.

Knowing fully well that there is an endless variety of GIS software or tools out there, processes that you need to execute to make things happen may vary in name and functionalities. Forget the beef between ArcGIS and QGIS, of which one is the better tool; if it serves your needs, then use it. You're not obliged to pledge loyalty to software or brands although you are encouraged to maintain integrity in your beliefs when it comes to corporate versus open source tools in the industry. Both choices come with their advantages and disadvantages. Yours truly uses QGIS and ArcGIS Pro interchangeably. If it doesn't work in ArcGIS Pro, which I use primarily, I'll jump to using QGIS. It's not a big deal. If it works painlessly, there is no reason to feel bad about using it.

So far, the content I have made emphasizes mostly on ArcGIS Pro or Esri products since using them is how I come to learn more about geology and geography. QGIS was a name I did not learn of in my university years when ArcGIS versions start with the digit 9️⃣, so you can catch my drift.

We can go on and on about theoretical stuff and our smarter pals usually knows what to do when faced with the tools. Unfortunately, I fall in the percentile that needed to land on the job to understand what on earth I am supposed to do. This series of videos are for those who have the same problem as I do and need to see the magic actually happening before knowing what to do. And for the most part, there are so many things to read and try out before you get it right. So hopefully, the demos can kickstart some thoughts or observation in the logic within the software's ecosystem and become more than just a technical power-user.

This week, I touched on some tools that I found helpful when dealing with point vector data, so feel free to check it out 👇🏻

Next week, I'm thinking of exploring some series of point analysis and space time cube is beckoning for me to test it out. Until then, stay cool and drop a word if you need any clarifications on the demos!

📑 International Climate Initiative (IKI) Land Use Plan: Green Initiative in the Heart of Borneo (HoB) Report

Tool: ArcGIS Pro 2.9.3 Technique: Overlay analysis, visualization via remote sensing technique

These maps are developed to aid or supplement the Natural Capital Valuation (NatCap) initiative. As cited by WWF:

An essential element of the Natural Capital Project is developing tools that help decision makers protect biodiversity and ecosystem services.

One of the site included in this initiative by WWF-Malaysia is the Heart of Borneo (HoB). Specifically for this exercise, the visualization of policy and land use eventually become the data input utilized in the tool InVest that generates the models and maps for the economic values of ecosystem services within the landscape of interest.

The generation of the data mainly includes superficial remote sensing to assess the status of the land use in the respective concessions using Sentinel-2 satellite image with specific band combination to identify tree cover, particularly mangrove forest.

code & run

Coding is one of the things I have aspired to do since like...forever! But finding a resource in-sync with my comprehension, schedule and able to retain my interest long enough is a challenge.

I have the attention span of a gnat so, I jumped everywhere! If I am not actively engaged with the learning, I just can't do it. And I know...we have DataCamp, Udemy, Khan Academy and even Kaggle...but I either can't keep up, too poor to pay for the full course or it couldn't sync with me enough. I believe I can say that most of the exercise doesn't 'vibe' with me.

Recently, I committed myself to my one passion; running. It's one of my favorite activities when I was back in school but the will to really run died a decade ago. I have recently picked up my running shoes and ran my little heart out despite having the speed of a running ant; aging perhaps? And I owe my hardcore will to the motivation of earning what I paid when I decided to join a 1-month long virtual run of 65km. It is called the 'Pave Your Path' virtual run organized by

Running Station

. Nailed it 2 days ago after 13 sessions of 5km - yes, you can accumulate the distance from multiple runs. It made me realize that...it's not that bad. The 'near-death' experience while running kinda turned me into a daredevil these days when it comes to undertaking some things I'd whine about doing a few months back.

"If I can go through dying every single evening for 5km long run...I can handle this,"

My thoughts exactly every time I feel so reluctant to finish some tasks I believe I could hold off for some time.

Naturally, I plan my work rigorously and despite the flexibility of my schedule and my detailed plans, I still have a hard time trying to nail the last coffin to my projects. Usually, it's due to my brain's exhaustion from overthinking or I am just truly tired physically. Which is a weird situation given I do not farm for a living. Even so, I was lethargic all the time.

But when I started running a month ago, things kind of fall into places for me. Maybe...just maybe...I've become more alert than I used to. I still have my ignorance of things that I believe do not concern my immediate attention but I seem to be able to network my thoughts faster than I used to.

It might be just me, feeling like a new person due to my sheer willpower to not burn my RM60 paid for the virtual run, but it did feel like there was a change.

For that, I managed to confirm what I have suspected all along - I am one of those people who love drills. I like things to be drilled into my head until I by-heart it into efficiency and then focus on polishing the effectiveness.

Thus...for coding, I committed myself to

freeCodeCamp

. By hook or by crook, I'll be coding by first quarter next year or someone's head is gonna roll!

It's an interactive learning experience simple enough for me to start, straightforward enough to not make me waste my time searching for answers and it's free. God bless Quincy Larson.

Going back to the program outlined in freeCodeCamp, I find it fascinating that they start off with HTML. I have no arguments there. My impatience made me learn my lesson - you run too fast, you're going to burn out painfully and drop dead before you halfway through. HTML is a very gentle introduction to coding for newbies since it's like LEGO building blocks where you arrange blocks and match two to create something. I didn't have to go crazy with frustration is I don't 'get' it. Yes, we would all want some Python lovin' and I think alot of coders I came to know have raved about how simple it is to learn. But I think, it is an opinion shared by 'experienced' coders who wished Python was there when they first started coding. Someone once told me, what you think is the best based on others' experiences may not be the best for you...and I agree with this. After alot of deliberations and patience at my end, starting over again this time feels, unlike the dreaded looming doom I've always had back then.

Are you into coding? What do you code and what's you're language preference? Where did you learn coding? Feel free to share with me!

survey123 offline

Survey123 for ArcGIS is perhaps, one of those applications that superficial nerds like me would like; it's easy to configure, kiddie-level degree of customization with 'coding' (for that fragile ego-stroke) and user-friendly template to use. 

No app development/coding experience is required to publish a survey form and believe it or not, you can, personalize your survey to not look so meh. 

It took me some time to stumble through the procedures of enabling this feature before I understand the 'ArcGIS Online' ecosystem to which this app is chained to. 

So how do we do it? And why doesn't it work pronto?

This issue may be due to the fact that when we first start creating our forms, we go through the generic step-by-step procedures that leave little to imagination what was happening. Most of the time, we're too eager to find out how it really work. 

When we publish a Survey123 form; be it from the Survey123 website portal or the Survey123 Connect for ArcGIS software, we are actually creating and publishing a folder that contains a hosted feature layer and a form. It is on that hosted feature layer that we add, delete, update or edit data it. From ArcGIS Online, it looks like any feature service that we publish out of ArcGIS Desktop or ArcGIS Pro, save for the special folder it is placed in with a 'Form' file. 

To enable any offline function in any hosted feature layer in ArcGIS Online, you will need to enable the 'Sync' feature. So far, in many technical articles that I have gone through to learn how to enable this offline feature always goes back to 'Prepare basemaps for offline use'. It is a tad bit frustrating. But my experience when deal with 'Collector for ArcGIS' gave me the sense of epiphany when it comes to Survey123. So when you have prepared your Survey123 form for offline usage and it still doesn't work...do not be alarmed and let's see how to rectify the issue. 

1. Locate your survey's hosted feature layer

At your ArcGIS Online home page, click 'Content' at the main tab. We're going to go directly to your hosted feature layer that was generated for your survey when you published. 

Locate your survey folder. Click it open 

In the survey folder, navigate to the survey's hosted feature layer and click 'Options' button; the triple ellipses icon

At at the dropdown, click 'View item details'. Please refer to the screenshot below: 

2. Change the hosted feature layer settings

At the item details page, navigate to the 'Settings' button at the main header and click it. This will prompt open the settings page for the feature layer. Refer to the screenshot below:

At the 'Settings' page, there are two tabs at the subheader; 'General' and 'Feature layer (hosted)'. Click 'Feature layer (hosted)' to configure its settings.

At the 'Feature layer (hosted)' option, locate the 'Editing' section. Here, check the 'Enable sync' option. This is the option that will enable offline data editing. Please refer to the following screenshot: 

Don't forget to click 'Save'

With this, your hosted feature layer which serves as the data model is enabled for synchronization. Synchronization helps to sync back any changes you've made when you're out on the field collecting data; editing, adding, deleting or update...depending on what feature editing you've configured. 

It's pretty easy once you get the hang of it and just bear in mind that the data hierarchy in the ArcGIS Online universe are as follows:

Feature layer (hosted) > Web map > Web application

Once you get that out of the way, go crazy with your data collection without any worries!

Peta Gunatanah Malaysia 2014 - 2018

Peta Gunatanah Malaysia 2014 -2018 ("Malaysia's Land Cover 2014 - 2018") web application is a platform generated for the Quality Assessment activity organized by Forest Research Institute Malaysia (FRIM) on 23rd June 2024.

The workshop aims to collect field/reference data from Malaysian's state agencies in the effort to verify the quality of the land cover classification output generated in support of CO2 release measurement from converted agricultural lands.

Participants are able access the app via conventional browsers from their mobile devices and submit drawings/sketches that they have captured within interactive data layers.

This web app aims to support direct input from source onto the task of improving the accuracy of the generated land cover maps. Vectors generated from this exercise are readily standardized with the required data scheme from quality assessment, making full use of the ArcGIS Online ecosystem full to a produce concrete output and actionable information.
