Given today’s performance expectations for online maps, it’s important to understand how to build map caches that deliver a fast and seamless user experience. Map caches are the recommended way to prerender maps at specific scales so that your ArcGIS server doesn’t have to create a new map image each time a user makes a request (i.e., pans, zooms, or makes another another click that requires a map redraw). After caching, you’ll see a dramatic improvement in map draw times. Continue reading
We’ve all heard a picture is worth a thousand words, but GIS users know that image data (imagery) is priceless for understanding what is going on in the world and how the world is changing. From emergency planning and disaster response to environmental monitoring, the applications in which imagery plays a starring role are numerous and the demand for high-resolution imagery continues to grow, especially as the price for storage media continues to fall.
Typically, imagery workflows have occurred outside the GIS. But integration of imagery and image analysis workflows as a core component of an enterprise GIS system has been a hot topic lately. Continue reading
When you think about the sheer number of Internet-based mapping applications being developed and distributed, it’s clear that the public’s interest in maps is at an all-time high. At the same time, awareness of the value of spatial intelligence is growing rapidly among government leaders and private sector executives. This is all good—as a GIS professional, you’re in the map business and you understand better than anyone the value of spatial intelligence for informed decision making.
Still, getting a mandate to deploy a GIS-enabled web mapping application can be challenging. The average GIS professional working today didn’t learn how to create web applications as part of their degree program.
