GIS Analyst Toolkit: ArcGIS Pro Create File Geodatabase

Shapefiles are so 1920s😁 Today many professionals work with File Geodatabases (.gdb) or Server Geodatabases(MSSQL / PostgreSQL / etc...).

In ArcGIS Pro, we just simply right click Databases in the Catalog panel and then click New File Geodatabase and then name the database and pick a spot you want to save the new Geodatabase.

Afterwards, we have a File Geodatabase that helps organize our data and allows us to accomplish more than what those old shapefiles can .

Keep GISing!!!!

The Mercator Projection And the False Narrative of African Overpopulation

The idea that Africa is "overpopulated" and that the poverty of its people is a function of geographical poverty is one of the most persistently promoted myths in western-dominated global discourse.

In this video, @Big_Mck forensically takes apart this myth, and the adjacent myth of Africa's small geographical size which has been promoted for centuries by the Mercator Projection, revealing them for the pernicious lies they are, and linking these lies totheir ultimate beneficiaries in the capitals of Europe and North America.

GIS Analyst Toolkit: ArcGIS Pro Embeddings

Embeddings are compact numeric signatures of spatial data. GIS analysts use them to find similar features, merge those signatures up to larger areas, and run pattern analysis without building a custom scoring model first.

Instead of writing long attribute queries or comparing raw pixels, you generate embeddings once and then ask" what looks like this?". The software compares vectors, not hand built rules.

What that unlocks:

Find similar places fast: Select a lift station, a neighborhood, or an image patch and find other locations with a similar visual or geographic signature even when the attribute tables do not match.

Work across scales: Generate embeddings at one level (parcels, hex bins, raster cells) and merge them up to ZIP codes, counties, or service areas without losing the semantic signal.

Skip a lot of feature engineering: Location, image, and text context get packed into one vector. That context can feed similarity search, clustering, or models without you stitching together dozens of demographic and land use fields first.

Discover patterns you did not code for: Embeddings pick up relationships that are not explicit in the schema such as similar site character, surroundings, and visual texture.

Stay in the GIS workflow: You can run the whole workflow in ArcGIS Pro. Open Embeddings from the Analysis tab, or use the GeoAI tools to generate embeddings, find similar features, merge embeddings across areas, and extract embedding values into fields for other analyses.

To me, it is especially useful for site selection, asset comparison, land use similarity, and image based inventory work.

GIS Analyst Toolkit: AcrGIS Pro Reports

Among the thousands of tools in a GIS workflow, reports are one of the few that belong in every toolbox. A map shows where something is, but a Report turns the same data into a document someone can actually use and puts it in a shareable package.

ArcGIS Pro's reporting tool is built for that job. Start from a layer or standalone table and then choose an Esri template (attribute list, grouped list, summary, etc...) or a custom template, then filter rows, pick fields, group and sort, and add statistics such as count, sum, mean, min, max, median, and standard deviation.

The result is structured like a real document. The report has page headers and footers, a repeating details section, and optional group headers and footers. You can add dynamic text, photos, charts, and map frames, then attach layout pages before or after the tabular sections. Export to PDF or Excel and keep the report in the project or save it as a reusable template.

If the deliverable needs more than a map screenshot, this is the tool that turns analysis into something you can hand off. For many scenarios, this tool can be a life saver.

Keep GISing!!!

"Nigeria is a shithole", but your supposed non-shithole country was a beneficiary of Nigeria taking all the bullets meant for it in the 70s and 80s, otherwise it might still be called "Upper Nyasaland" with cities named "Salisbury" and "Leopoldville", and you would still need written permission to leave your designated "Bantu reserve area" and travel to other parts of your country.

At least 3 Nigerian presidents have been murdered in office for protecting African interests, including one whose assassination was personally ordered by Henry Kissinger for leading an anti-apartheid vote at the AU against US instructions just 30 days before he was shot.

Name another country on the planet where 4 different presidents have been killed in office since 1966, and each of these assassinations was a foreign-driven operation. Nearly all of the limited freedom from direct colonialism that most Africans have today is a barge floating on a river of Nigerian blood - apart from DR Congo, which is nearly 3x bigger than Nigeria, no country on this continent has lost more people to foreign-backed wars and insurgencies.

Many of you have gotten way too comfortable casually disrespecting Nigeria because you are not aware of the terrible price it has paid to give you the limited freedom that you have. If Nigeria had spent all those decades acting like Kenya and collaborating with your enslavers, by now you would be in your Bantu reserve with no internet access reading smuggled magazines with photos of Lagos and Abuja, and it would look like a different world to the one around you.

Nigeria will not remain in its current debased state indefinitely. It will surely rise again and when it does, a lot of this casual disrespect towards Nigeria and Nigerians will be revisited. You will explain precisely what you mean by "Nigeria is a shithole" all the way from Mpumalanga.

Nobody is asking for any grace or help from you (which will never come anyway). You're just being notified.

GIS Analyst Toolkit: ArcGIS Pro Notebooks

When it comes to Notebooks in ArcGIS Pro, you are not in Kansas anymore, Dorothy.

The familiar point and click GIS world of tools, geoprocessing panes, and map views is still right there but Notebooks open a different landscape. You are now working in an integrated Jupyter environment inside the desktop application, where live Python, maps, charts, narrative text, and results all live in one document. This also allow you to hook AI into your ArcGIS Pro application, which brings a new world to your vision.

In ArcGIS Pro, Notebooks let you:

☕️ Access layers and map contents directly by name (or by path)
☕️ Run geoprocessing tools from code and have outputs land on the active map

☕️ Honor current selections and environment settings

☕️ Mix ArcPy, the ArcGIS API for Python, pandas, NumPy, and other libraries already included with Pro

☕️ Document the workflow as you go with markdown, so the analysis is reproducible and shareable

☕️ Iterate quickly: clean data, run spatial stats or machine learning, visualize, refine, and save everything inside the project

Instead of jumping between the Python window, a separate Jupyter session, and the map, you keep the map and notebook side by side. Results appear in geographic context immediately. You can prototype an analysis, automate a repetitive task, explore patterns with open source libraries, or build a documented workflow that a teammate can open and understand.

Notebooks turn ArcGIS Pro from a powerful desktop GIS into a spatial data science workstation. The yellow brick road of traditional tools is still available, but Notebooks give you a much bigger and flexible world to work in.

Keep GISing!!!

Nigeria ranks near the bottom on download speed (111th out of 119 countries) with a median real-world download speed of just 5.3 Mbps.

Globally, the median internet speed sits around 34 Mbps to 40+ Mbps, while standard 4G/5G mobile connections in developed tech markets easily average 100 Mbps to 200+ Mbps.

A worker in the UK or France spends less than 1% of their monthly income for unlimited usage.

In contrast, an average worker in Nigeria who spends ₦10,000–₦15,000 a month on data is giving up 10% to 20%+ of their monthly earnings.

GIS Analyst ArcGIS Pro Tool: Relationship Class

Not only do GIS Analyst have to know about statistics, but GIS Analyst also have to know a little about database design too. Knowing about database design helps a GIS Analyst actually model how things work in the real world.

A Relationship Class in ArcGIS Pro is a persistent geodatabase object that stores the association between records in two tables or feature classes (an origin and a destination). It is defined by matching key fields (primary key in the origin, foreign key in the destination) and lives in the same geodatabase as the participating data.

What it is used for:

(1) Linking features to other features, features to tables, or tables to tables so you can navigate related records.

(2) Enforcing referential integrity (especially with composite relationships, which can cascade delete destination records when the origin is deleted).

(3) Supporting cardinality of 1:1, 1:M, or M:N.

(4) Optionally storing attributes that describe the relationship itself (attributed relationship classes).

(5) Applying relationship rules and messaging so edits in one class can automatically affect the related class.

It is more permanent and behavior rich than a temporary Relate or Join. Relates and joins exist only in a map or layer but a relationship class is stored in the geodatabase and is available to anyone who can access that geodatabase.

Once you understand the concept of Cardinality such as (1:1 1:M and M:N) you will be on your way creating elaborate data models that represent the real world.

I think this is a skill issue: as someone who's been working with agents and agentic GIS frameworks for the past few years I believe AI can definitely create maps! Accurate and well-designed maps. My general advice is to not ask for image generation because this will lead to ridiculous results. Instead ask your AI agents to write a script in familiar language (Python, R etc.) using specific packages. Define data sources and boundaries. If needed, explain GIS operations it must take to finish work (merge, crop, intersection etc.). Add info om colorblind palettes, north arrow, CRS, resolution. All of this should be either part of your AGENTS.md and/or skills md files). Here are a few maps I built with my package forge3d and AI agents: https://t.co/8KnQv9dJl8.

GIS Analyst Tool: Buffer

The Buffer tool is a true classic in GIS analysis. It is simple in concept, yet remarkably powerful in practice. The buffer is far from being just a basic or outdated feature, it remains one of the most versatile and frequently used tools in a GIS Analyst’s analytical toolbox.

At its core, the Buffer tool creates a new polygon feature (or set of features) that represents a zone of a specified distance around an input point, line, or polygon. This "buffer zone" can be fixed distance or variable distance, and it can be applied to single or multiple features at once. The result is a spatial area that defines proximity, influence, or risk around the original features.

Even though buffering is one of the oldest and most fundamental geoprocessing operations, the buffer strength lies in its flexibility and the analytical depth it unlocks when combined with other tools such as the Apportion Polygon. Analysts routinely use buffers to answer questions such as:

1⃣ What lies within X meters/kilometers of a feature?
2⃣ Which areas fall inside a potential impact or service zone?
3⃣ How do proximity relationships change when distances vary?
4⃣ What population (or other attributes) is contained within the buffer?

Because buffers can be dissolved, combined with a union, intersected, or used as selection layers, buffers serve as a foundational building block for more complex spatial analysis rather than an end product themselves.

Here are some common applications for buffers:

1⃣ Environmental & Planning
Creating setback zones around rivers, wetlands, or protected habitats and defining noise or pollution impact areas around industrial sites.

2⃣ Business & Site Selection
Analyzing market catchment areas or drive time / service area equivalents around stores or facilities.

3⃣ Infrastructure & Utilities:
Defining rights of way, maintenance corridors, or exclusion zones along roads, railways, or power lines.

4⃣ Public Safety & Emergency Response:
Establishing evacuation or response zones around hazardous facilities, pipelines, or incident locations.

On that note, keep GISing and remember, the simplest tools pack the biggest buffered punch.😀🤣
