The idea for the product HTML ImageMapper dates back to the year 1998, when ESRI’s ArcView 3.1 made it possible for the first time to export map images into a browser-enabled format (JPEG). In the spring of 1999 the HTML ImageMapper 1.0 was brought on the marked as an extension to ArcView 3.1. The product line HTML ImageMapper 3 as an extension to ArcView 3 was continued, currently, the HTML ImageMapper 3.5 is available as the compatible extension to ArcView 3.
In the course of ArcGIS (ArcView 8), alta4 developed in 2001 the first extension worldwide to ArcGIS: the HTML ImageMapper8. After the versions 8 and 9, version 10 for ArcGIS 9.1 has been on the market since July 2006. This version constitutes a big progress. The newest web technologies, like AJAX and DHTML, have been used in its realization.
The result is a surface similar to Google Maps, with dynamic zoom and pan without reloading the site.
In the current version ImageMapper NG the authoring system has been completely remodeled and developed under Microsoft Visual Studio.
