The PIM Feature, Introduction and Application in GIS

In a previous post, we discussed the meaning of the pimConfiguration as a collection of elements in the Platform Independent Model (PIM). One of those elements (in fact, the most important geospatial one) is the pimFeature. The pimFeature is that table/object that defines the geometric object that gets displayed on the map, sometimes called the […]

Exploring the PIM: Versions and Users

This post will begin to introduce PIM and PIM API organization. The PIM API is coupled with the tables and views in the PIM based on the rule set discussed in the previous post. The fundamental object (and table) in the PIM API and the PIM is the pimVersion. Each element in the PIM and […]

Understanding Geospatial Data Rules in the Platform Independent Model (PIM)

This post continues a series describing our approach to using a platform-independent approach to managing data models and standards. In any situation where a geospatial data model is agreed upon and adopted by multiple participants, management of the model itself becomes a significant issue. Over time, modifications to the model are required. Such modification can […]

Applying Flexible, Yet Standard, Geospatial Conventions

Previous posts have touched the problems that traditionally face those wanting some geospatial consistency in data collection, data presentation, and data understanding. These issues drive much of the continual interest and push for increased Metadata and many of the “Use Liability” clauses that are attached to current datasets. After all, if you don’t really know […]

Expanding Usefulness of Geospatial Data Standards

Background: While many organizations see the clear advantages of establishing and using geospatial data standards, obtaining compliance from constituents continues to be a frustrating, and costly, problem. Users are frequently reluctant to adopt a new standard given the potential cost of modifying applications that use an existing, custom schema or simply having a ‘not invented […]

Exporting ESRI Silverlight Graphic Layer to Google Earth

On my current project I was tasked with exporting our map layers to Google Earth. This was simple for the ESRI ArcGIS Server layers, since Server has out-of-the-box support for KML. However, as would be the case, we don’t use ArcGIS Server for all of our layers. We also use ESRI Graphic Layers for rendering […]

Using Arc2Earth for Tile Caching across Air Gapped Networks

Update 9/15/18 – Arc2Earth no longer offers subscriptions or services.  Zekiah supports many organizations, especially in the federal government, that have a need to run ArcGIS Server on networks that are not connected to the internet. Oftentimes, these organizations use tiled basemaps that are built from data or services that are available (whether free or […]

Understanding SDSFIE 3.0 Compliance

One of the more critical, and somewhat confusing, concepts in the SDSFIE 3.0 is the notion of what constitutes a ‘compliant’ data set. SDSFIE 3.0 offers considerably more flexibility in schema options than earlier releases. This capability was created to permit individual DoD users some naming options to accommodate existing legacy applications that use geospatial […]

Spatial Data Standards for Facilities, Infrastructure and Environment (SDSFIE): Five Fundamental Tools

The Spatial Data Standards for Facilities, Infrastructure and Environment (SDSFIE) is the single Department of Defense spatial data standard that supports common implementation and interoperability for installations, environment, and civil works missions. SDSFIE is being managed by the Defense Installations Spatial Data Infrastructure (DISDI) Group. The DISDI Group is a formal governance group reporting to […]

Integrating SharpMap with the Esri ArcGIS API for Silverlight

Note: The project described in this post also makes use of ArcGIS Server. If you intend to use the Esri ArcGIS API for Silverlight/WPF without ArcGIS Server, you should review the license agreement. If you have spent much time with the Esri ArcGIS API for Silverlight, you know it provides a lot of capabilities and […]
