Telling thematic stories in ArcGIS Online

By Kenneth Field (Research Cartographer), Damien Demaj (ArcGIS Online Cartography) and Linda Beale (Geoprocessing)

Telling thematic stories in ArcGIS OnlineAt the 2012 Esri Education GIS Conference and the 2012 Esri International User Conference, we demonstrated how you can build informative thematic maps using the ArcGIS System.  The purpose of the sessions was to take relatively simple datasets and create a range of alternative thematic map types that told a story in different ways.  This demonstrated the techniques for creating the maps using ArcGIS for Desktop as our authoring environment and ArcGIS Online as our publishing mechanism.  As the XXX Olympiad is currently taking place in London, UK we illustrated how alternative maps can be made to tell different stories of the relative success of nations over the period since the first Olympic games in 1896.

Developer Summit Europe

To build on the success of recent Developer Summit in California, we’ve decided to take the event on the road. Esri will be hosting 3 Dev Summits in Europe this September.

I hope developers from all over Europe and the world will come together in Rotterdam, Berlin or London (all 3 if you want). The technical sessions will focus on becoming more effective at building web, mobile and desktop applications. Senior Esri development staff will be presenting so you’ll get a chance to see what’s coming next. Registration information will be available soon but mark your calendar now and plan to join us in Europe.

Be successful overlaying large, complex datasets in Geoprocessing

Spatial datasets often have large numbers of features.  Furthermore, these datasets may also contain individual features such as road casings that are very large and complex.

As a result of such large datasets, massive amounts of feature overlap (number of features and complexity of the overlapping features) within feature classes can result in a geoprocessing tool failure or poor performance.  These failures are often due to system resources limitations, mismanagement of resources, “bad” data, or massive overlap in an area that cannot be processed within the available resources.  Failure messages such as “Invalid Topology [4GB_FILE_LIMIT] “, or “Out of memory” can occur.  In rare cases, an application crash is possible.

At 10.1, significant work has been done for managing the processing of large complex data.  We have removed internal limitations and overhauled our overlay engine’s memory management.  Some overlay processes that previously failed can now complete successfully, and with reasonable performance.  However, following these guidelines and best practices should ensure your large overlay processes complete successfully.

Using a mapmaking checklist for map design

By Kenneth Field, Research Cartographer, and Damien Demaj, Online Cartographic Product Engineer

Checklist - Thumbnail

We all have favorite maps that we think are great, but rather than just saying a map looks great, how many of us are able to take a critical look at it, evaluate it, and explain why it looks great? Having the ability to reflect on and evaluate maps as information products is important to understanding effective cartographic design so you can optimize communication of the intended message in your own maps as well as be able to understand why other maps work. In this blog entry, we’ll briefly look at some static maps and a web map to see what we think makes them great and then show you how using a checklist gives you the tools to reflect on maps in the same way. Continue reading

An intelligent map checklist

Figure 1: What you see in your MXD’s legend is what appears in your web map.  Avoid cryptic file names, field names and legend labels that report numbers but not context.  The legend in this example uses qualitative phrasing (e.g. “Great Increase”) as well as numeric (e.g. “More than 1.5%) because the audience likely has no idea what constitutes significant increases or decreases.

When you create an intelligent web map or map service, you are sharing something that you hope will stand on its own and be useful to others.  How can you deliver a map that is both attractive and useful for … Continue reading
