ThinkGeo Maps Query Sample Spotlight: Cities Affected by Nuclear Disasters

The settlements affected by Chernobyl’s 1986 nuclear accident

There have been a handful of nuclear power plant events that have had significant consequences for people, the environment and the facilities and workers of the plant. Sometimes the scope and radius of the area impacted by these events is minimized or not completely understood. Maps can help in painting that picture. ThinkGeo Cloud can go the extra mile and stress the importance and the magnitude of such events.

ThinkGeo’s Maps Query Service can be used in a near-limitless variety of applications, but for this use case we wanted to show off the ease of putting a map together that focuses on finding points within a custom area shape. Continue reading

Maps Query Service added to ThinkGeo Cloud

Cities affected by a threatening Atlantic Hurricane

ThinkGeo’s Cloud Maps Spatial Query Service is a data allocation haven. With it, you can free-draw, set lines and/or polygon contours for any portion of ThinkGeo’s World Maps and then extract a bevy of spatially-related data. For example: if your input shape contains waterways, buildings, railways, points of interest, etc., you can
query them and get instant highlighted results from your search. Through our demo center, users can experiment with a variety of layers and query types to customize their experience and they can even set their max results to a custom value. Continue reading

A Look Ahead at ThinkGeo Cloud

With a major .NET evolution around the corner; ThinkGeo is primed to make the most of the latest environment enhancements. Our library of SDKs are being re-written to take advantage of the technological climate ahead of us, and will support .NET Core 3.0 natively when the new version of Microsoft’s development framework launches in the fall. ThinkGeo Cloud uses our SDKs as its main engine, which means that our Cloud services will be more performant, more responsive and more memory-efficient.

Our Cloud offering keeps strengthening, and in line with that notion we aim to add some of our most asked-about features as well as some completely new and innovative services to ThinkGeo Cloud over the course of 2019. Continue reading

Querying & Editing GRID Files in Map Suite

Arc/Info ASCII Grid is one of many supported raster formats in Map Suite. In addition to displaying ESRI grid files you can also query and edit the data in Map Suite. Here is the latest sample demonstrating the ability for the user to select an area of the grid (raster layer) by using a spatial query, and then updating the underlying cell values with a user specific value.

This has been integrated as a core feature in Map Suite therefore it can be used in the web or desktop products. Continue reading

Find what’s nearby by using Distance Queries

In addition to spatial querying GIS developers should also consider adding distance querying functionality to allow users to make spatial decisions. In mapping applications it can be useful to find features within a certain distance. For example, let’s say you want to find the number of gas stations that are within a given distance from your location. Distance querying can help you answer such questions.

Map Suite offers a couple different Distance Query APIs to help you build your application including:

• GetFeaturesNearestTo – finds the nearest feature from your location. Continue reading

Add Spatial Querying Capabilities to Your Maps

Have you considered using GIS to make spatial decisions? Spatial querying is a powerful tool that helps you make decisions based on geographic relationships between different features. You might be wondering why you would want to use spatial queries. Some good examples of spatial querying might be the need to know the coverage area for a Wi-Fi system or the proximity of possible hazardous materials to schools so that plans can be made accordingly and much more.

There are several types of spatial queries available to you:

  • Within – Selects features that the querying feature fully contains.
  • Continue reading Leave a Comment
