This sample shows how to display a map using data loaded from PostgreSQL PostGIS.
This sample shows how to display a map using data loaded from a ShapeFile (.shp).
Heat maps are a technique increasingly used
in various fields such as biology and geology. They are also used for displaying areas of web pages that are
most frequently interacted with.
In this sample, we apply this concept to geographic maps. Heat maps are a great way to give users a visually compelling representation of the distribution and intensity of geographic phenomena.
This sample simply adds an ECW layer to show a satellite image on the map.
A "standard image" is one of several formats supported natively by the Windows operating system; these include .bmp, .png, .gif and so on. In this sample we'll show you how to load these types of images onto a map with just a few lines of code.
This sample demonstrates how to add your own data to a ShapeFile feature layer.
In this sample, we show you how to set different styles for the map or load different data to the map
at scales from 1:10,000 to 1:100,000,000.
This sample is also an opportunity to review the very basic concept of scale in GIS. The easiest way to think about scale is to consider it a ratio between what you see on the screen and the real world. So, if the scale is 1:10,000 it basically means that one centimeter (you can use any unit) on the screen represents 10,000 centimeters (or 100 meters) in the real world. Of course, there are some intricacies involved with calculating the scale for a map according to its projection, etc. But if you think of scale in that very simple way, you will have a general idea of what your map's scale truly represents.
This sample shows how to apply a filter to your data before rendering.
This sample shows you how to convert a geographic shape to WKB (Well Known Binary) and back.
This sample shows you how to convert a geographic shape to WKT (Well Known Text) and back.
