Using KML for Thematic Mapping

Posted on November 30, 2009. Filed under: Uncategorized |

If you haven’t already done so head over to Bjorn Sandvik’s Thematic Mapping Blog and download a copy of his research paper: Using KML for Thematic Mapping.  It’s well worth the read.  You should also check out his Thematic Mapping API.  Thematic Mapping API is a new JavaScript library which allows you to create KML based thematic maps from your own data source using JavaScript.

ArcGIS Online Moving to Google Maps/Bing Tiling Scheme

Posted on November 24, 2009. Filed under: ArcGIS Server, ESRI |

Late last week ESRI announced that its ArcGIS Online services will be migrating to the Mercator-based tiling scheme used by Google Maps and Bing Maps by the end of the year.  Previously these services have used the WGS 1984 geographic coordinate system with a 512 x 512 pixel size.  Google Maps and Bing use a modified Mercator projection with a 256 x 256 tiles size. The differences between ArcGIS Online and the popular Google Maps and Bing tiling schemes caused problems for many organizations.  According to ESRI,

Some organizations struggle with choosing either the ArcGIS Online tiling scheme to match their ESRI software stack, or the Google / Bing tiling scheme to match a better-known standard. With a unified tiling scheme for the three services, the decision gets a lot easier.

The post goes on to discuss the advantages and challenges of switching to the new tiling scheme and also discusses a workflow for caching your maps in the new scheme.

Poll Results: GIS Web Application Development Platform

Posted on November 12, 2009. Filed under: ArcGIS Server, ESRI, Google Maps, OpenLayers, Virtual Earth |

Our recent poll (it’s not too late to vote) concerning current and future plans regarding your development platform for web mapping applications resulted in some interesting patterns.   You can view the results here.  We’ve had 643 as of now.

  • ArcGIS Server and it’s many developer choices accounted for 208 votes or 32%.
  • The ArcGIS Server JavaScript API appears to be the #1 choice among ArcGIS Server developers with 63 votes.
  • The Flex API is running second behind the JavaScript API
  • Interestingly, more people are still developing on ArcIMS than are using the ArcGIS Server Java ADF
  • Open Source development platforms including OpenLayers,  MapServer, and GeoDjango are increasingly popular with 221 votes between them or 34% of the vote.
  • OpenLayers was the leader of the pack….no surprise there.
  • The Google Maps API continues to be a popular choice with 82 votes or 13%.
  • Bing Maps remains far behind Google Maps
  • A fair amount of votes in the “Other” category with 70 votes.

Coming Soon! – Google Earth and ArcGIS Integration for Local Government Users

Posted on November 5, 2009. Filed under: Arc2Earth, ESRI, GeoSpatial Training Services, Google Earth, KML |

GeoSpatial Training Services will be releasing a new instructor guided, Internet based course in the near future.

Google Earth and ArcGIS Integration for Local Government Users

Most local government agencies have large collections of GIS data in various formats including shapefiles, geodatabases, grids, tins, CAD, and others. Sharing this data with colleagues and the public is often a challenge. Before distributing data you have to answer many questions. Does my end user have the appropriate software to view the data? Do they know how to use the software? Do they understand how to add the data into the viewer? Should I create a web mapping application for end users? Converting your existing GIS data to a Google Earth KML format offers many advantages in terms of data distribution to end users and it also offers many new ways of presenting information. This course, geared specifically for local government GIS specialists, will teach you techniques for converting your datasets, creating compelling and interactive Google Earth displays, and sharing the data with your end users.

Notes:

  • Register your entire GIS group for $199.00 (up to 8 people)
  • This course makes extensive use of Arc2Earth. You will be provided with an evaluation copy of Arc2Earth to use during the course
  • Exercises and data will focus on typical local government datasets

Modules

  • Benefits of Converting ArcGIS Data to Google Earth Format
  • What Google Earth Version Should I Use?
  • KML: The Language of Google Earth
  • Tools for Converting ArcGIS Data to Google Earth
  • The Easy Stuff: Convering Points, Lines, Polygons, and Graphics
  • The Not So Easy Stuff: Displaying Spatial Analyst Grids, Aerial Imagery, and Other Image Files
  • The Hard Stuff: Techniques for Displaying Large Datasets
  • The Fun Stuff: 3D Data Displays, Geography with a Time Element, Info Balloons with HTML, Images, and Video, Guided Tours
  • Eye Candy: Creating Legends and Logos
  • Google Earth without an Internet Connection
  • Techniques and Tools for Sharing Google Earth Data with End Users

Students will learn how to use Geodatabases by working through two realistic projects. The first project is preparing data for a burn plan on the Florida Panther Refuge; the second is working with stream data from the Wenatchee National Forest to analyze fish populations

Mastering the ArcGIS Server JavaScript API
January 11th – February 19th
Our Mastering the ArcGIS Server JavaScript API course is a series of 7 modules that will teach you how to build high performance, attractive Web mapping applications using the lightweight, browser based ArcGIS Server JavaScript API.
