Added Open Source GIS Tool Files

Project under Dedicated Mentorship Program in Code 4 Gov Tech.

The "Open Source GIS Tool" aims to develop a user-friendly and accessible GIS tool to help users use geospatial information and geographic data to solve real-world problems. The tool will empower urban planners, engineers, policymakers, and community stakeholders to identify suitable locations for various projects (like sustainable water management, efficient resource distribution, goods storage, other location-based projects etc.) and design their plans accordingly.

Poem

🐇 In a world of maps, we leap and bound,
With tools and data, new wonders found.
From Delhi's streets to buildings tall,
Our GIS Tool helps us see it all!
So hop along, let's explore the land,
Together we'll analyze, hand in hand! 🌍✨

Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    -- I pushed a fix in commit <commit_id>, please review it.
    -- Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    -- @coderabbitai generate unit testing code for this file.
    -- @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    -- @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    -- @coderabbitai read src/utils.ts and generate unit testing code.
    -- @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    -- @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

1-1: Consider using a hyphen in the title.

"Open Source" is a compound adjective modifying "GIS Tool". Consider using a hyphen for better readability:

-# Open Source GIS Tool

3-4: The summary looks good!

It clearly outlines the project's objectives, target users, and potential applications.

Just one small nitpick - consider using a hyphen for the compound adjective "user-friendly":

47-49: Ignore the missing punctuation warnings.

The static analysis tool has flagged potential missing punctuation issues in lines 47 and 49. However, upon closer inspection, these appear to be false positives. The code is using valid JavaScript object notation and function calls, and no punctuation is missing.

Feel free to ignore these warnings.

1-1: The geographical data in the JSON file looks good!

A few additional verifications I would suggest:

  1. Confirm that the place_id values are unique across all the objects.
  2. Validate that the lat and lon coordinates are within valid ranges (-90 to 90 for latitude and -180 to 180 for longitude).
  3. Check that the GeoJSON data in the geojson property follows the correct format and structure for the Point, Polygon and MultiPolygon types.

1-4: Specify the versions of the dependencies.

The choice of dependencies aligns well with the project's objectives of geospatial data processing and visualization. However, to ensure reproducibility and avoid compatibility issues in the future, it is recommended to specify the versions of the dependencies.

Consider updating the requirements file to include the versions of the dependencies, like this:

-earthengine-api
+earthengine-api==0.1.337
-osmnx
+osmnx==1.2.2
-mapclassify
+mapclassify==2.4.3
-geemap
+geemap==0.19.0

You can find the latest versions of the dependencies on their respective PyPI pages:

218-218: Remove the unused start_name variable assignment.

The static analysis tool has flagged the start_name variable as assigned but never used. Consider removing the assignment to improve code clarity.

79-79: Remove the assignment to the unused variable scale.

The static analysis tool has flagged the assignment to the variable scale as unused. Consider removing the assignment to improve code clarity.

1-17: README file looks great!

The README file provides a clear and concise overview of the Open Source GIS Tool project. It aligns with the PR objectives and provides useful information for users to understand and run the tool. The content is well-structured and easy to follow.

Some key points:

  • The summary section effectively communicates the purpose and target audience of the tool.
  • The use section clearly lists the main files of the project.
  • The steps section provides straightforward instructions on how to install dependencies and run the tool.

Overall, the README file is well-written and serves as a helpful introduction to the project.

The goal21 function correctly prompts the user to choose a facility and returns the selected facility number. The implementation is straightforward and serves its purpose well.


101-198: The goal2 function is well-implemented.

The function effectively utilizes the ox library to find the shortest path between two selected warehouses and creates an interactive map using geemap to display the results. The code is well-structured and uses appropriate libraries for the task at hand. The use of the goal21 function for user input is a good design choice.

The conversion function correctly converts a string of longitude and latitude to a tuple of floats. The implementation is straightforward and serves its purpose well.

Also applies to: 222-228


257-294: The main program logic is well-structured.

The main program provides a user-friendly interface for interacting with the different features of the GIS tool. The menu-based approach allows the user to easily select the desired operation, and the corresponding functions are called based on the user's choice. The use of a while loop enables the user to perform multiple operations before exiting the program, enhancing the overall user experience.
