051] Global Mapper - Refining Path Profile 2: with ChatGPT

Continuing from the last session, I had more conversations with ChatGPT. It really feels like talking to a human.


"Before we begin, if you missed the previous session, check it out here:"



In the previous post, I manually designated the "site" area. In other words:
[img 1 : Intersection of the profile line and the project site boundary in Global Mapper]
[img 1 : Intersection of the profile line and the project site boundary in Global Mapper]

As shown in the image above, I manually identified the range where the cross-section line intersects with the project site boundary and input that range when ChatGPT generated the graph.

However, looking at the contents of the exported CSV file for the path profile:

[img 2 : Path profile CSV data displayed in Windows Notepad showing coordinates]
[img 2 : Path profile CSV data displayed in Windows Notepad showing coordinates]

It doesn't just contain distance and elevation; it includes the raw coordinate values (X, Y).

The Potential for Automation

When you export a path profile in CSV format, you have various options:

"Save Path to CSV File (XYZ, Distance, Slope)..."

Because coordinates and elevation values are included, we can infer a possibility here. If we provide both the path profile CSV data and the project site CSV data to ChatGPT at once, it should be able to identify the project range automatically without me having to tell it manually.

Exporting the Project Site Area as CSV

Recently, we learned how to add points, lines, and areas using CSV files. (Refer to 049] Global Mapper - Adding Points, Lines, and Areas using CSV files).

Now, let's export the project site as a CSV area file.

[img 3 : Right-click menu on the layer to access the Export Layer to New File option]
[img 3 : Right-click menu on the layer to access the Export Layer to New File option]

Select the project site layer, right-click, and choose Layer - EXPORT - Export Layer(s) to New File...

When the layer selection window appears:

[img 4 : Selecting the specific 'area' layer for export]
[img 4 : Selecting the specific 'area' layer for export]

Select only the layer containing the project site area and click OK. When prompted to choose the export format, select CSV and click OK.

CSV Export Settings

When the CSV Export Options window appears, configure it as follows:

[img 5 : Detailed CSV Export Options including Field Separator and WKT format]
[img 5 : Detailed CSV Export Options including Field Separator and WKT format]

Set the Field Separator to "Semicolon" and check "Export Area and Line Features (Use WKT Coordinate Format)". This is crucial for ChatGPT to understand the geometry. Click OK to save the file.

(Note: From the next session, I will skip capturing previously explained processes and just describe them in text.)

Conversing with ChatGPT

Now we have two files: the path profile CSV and the project site area CSV. It's time to talk to ChatGPT. Log in to ChatGPT and upload both files.

[img 6 : Uploading PathProfile.csv and Site.csv to the ChatGPT interface]
[img 6 : Uploading PathProfile.csv and Site.csv to the ChatGPT interface]

I uploaded the project site and path profile files and requested a graph using the "Path Profile Instructions" I developed during our previous conversations (I've added several new features since then).

The Result?

It successfully identified the boundaries and marked the highest and lowest points within the project area. I also added another feature.

[img 8 : Global Mapper view of a profile line crossing multiple sections of the site]

I tried creating a cross-section line that enters and exits the project area multiple times, as shown above.

And the result?

[img 9 : Complex profile graph showing multiple site intersections (site 1, site 2) with elevation callouts]
[img 9 : Complex profile graph showing multiple site intersections (site 1, site 2) with elevation callouts]

Brilliant! It correctly identified "site 1" and "site 2".

It’s not difficult at all. Try chatting with ChatGPT to create a profile that fits your unique needs and style.

That’s all for today!

001] Global Mapper - Creating DEMs

Image
This is the first session of the Global Mapper series. Among the many things you can create using GIS software, I plan to cover topics essential for preparing landscape-related reports, such as: Creating a DEM (Digital Elevation Model) Using Online Maps Contour, Slope, and Aspect Analysis Path Profiling (Terrain Sections) Viewshed Analysis Using the Map Layout Editor for saving images in Global Mapper As with my CityEngine series, I believe in getting started first to build a framework as posts accumulate. I won't go into every tiny detail right from the start; instead, I will provide deeper explanations and supplementary information as we progress. First, you'll need to download the trial version. If you visit the  Blue Marble Geographics  website, you will see a menu for a "Start Free Trial." Please note that personal emails (Naver, Gmail, etc.) are generally not accepted; you must use an email associated with a company or an educational institution. Once your email...

First, please run Global Mapper. [img 1 : DEM created in Global Mapper with a line segment added for profile analysis] With the DEM created, add a line segment. Now, let's extract the terrain profile. [img 2 : Accessing Path Profile through the Analysis/Measurement menu] After selecting the line segment, right-click and select Analysis/Measurement - Path PROFILE . The Path Profile result window will appear. [img 3 : Standard Path Profile result window in Global Mapper] As you can see, it's quite basic. While it's functional enough to convey information, I thought about refining it using chatGPT. To do this, save the results as a CSV file. [...
