Introduction: I am currently working on a requirement for one of our custom web mapping solutions that needs to authenticate with the ArcGIS Platform in order to access web maps and layers. The objective is to create an API for authentication, which can be called in the application to perform authorization and authentication. ArcGIS REST JS is a lightweight collection of JavaScript modules that allows users to access ArcGIS services and develop mapping and spatial analysis applications....

In this article, I will walk you through the process of ingesting geospatial data from the Overture Maps Foundation into Snowflake, using a step-by-step approach. Additionally, we will leverage the Snowflake-Koop provider to access and serve the ingested data as a GeoService. What is Koop.js ? Geospatial data server for the web; built using Node JS w/ javascript (a.k.a RESTful web server) Transform/serves data from from remote APIs with HTTP requests Support geospatial operations Built-in support for Geoservice Spec (for ArcGIS clients) “Plugins” allow quick and customuze deployments Underlying tech for custom data feeds in ArcGIS Enterprise....

By Year and FIPS/ASD code 2. By Year and Bounding BOX 3. By Year and multiple points 4. By Year and upload vector files (shp file in zip format) Click here for the API examples...

This is an introductory guide on using QGIS SCP (Semi-Automatic Classification/Supervised Classification) for classifying land cover using Landsat data. Before we dive in, let’s start with some key basics. Spectral Vs Informational Classes: Spectral Classes : Group of pixels that are uniform with respect to their pixel values in several spectral bands Informational Classes : Categories of interest to users of the data (i.e Water, Urban, Agriculture, Forest etc) Image classification is the process of GROUPING spectral classes and assgining them informational class names...

I’ll share some of good technical articles and blogs which I came across. Awesome Vector-tiles . List of parsers and generators, clients and geospatial tools. What are Vector-tiles? . Good summary of vector-tiles and why should we care Awesome MapBox Resources - List of external resources if you are using Mapbox Tiling - Good reading on tiling. Must for any geospatial Engineer Src vs Flat Layout - Gives good undertsnading of python packaging and layout structure....

This post walks you through the process of creating an API with geospatial capabilities using FastAPI and Pixi. Many data science and machine learning projects today use Conda for environment management and Poetry for package management. Using Poetry and Conda together in Python projects creates challenges due to their conflicting approaches to environment management and dependency resolution, often leading to inconsistencies in package versions and sources. The combination increases complexity in CI/CD pipelines and Dockerfiles, making it difficult to maintain consistent environments across different stages of development and deployment....
