Generating Physical Schemas From a PIM

A while back, my colleague Barry Schimpf touched upon some of the tools that we use in conjunction with the Platform Independent Model (PIM). Today, I will delve into one of the tools we use to generate physical schemas from the PIM. Before, I jump in, let’s review what a PIM is and what it […]

Exporting ESRI Silverlight Graphic Layer to Google Earth, Part 2

A while ago Sky wrote a blog post about exporting an ESRI Silverlight graphic layer to Google Earth. The post explained how to export point data to KML but recently someone inquired on how to also do line and polygon layers. In this post I will explain how to do so.

Embedding Maps in SQL Server Reporting Services Using ArcGIS Server

The combination of Microsoft and Esri products is common across Federal information infrastructures and, as a result, we find ourselves integrating these tools often. SQL Server Reporting Services (SSRS) is still a widely-used solution for generating dynamic reports in many government settings. Invariably, some users want to use their Esri tools to embed maps into […]

Automation of Semi-Dynamic Maps with Geoprocessing

With the increasing focus on information security across all sectors of government, IT policies are placing increased restrictions on information architectures, including GIS. While these restrictions may not prevent the development of a robust enterprise geospatial architecture, the approval and accreditation processes can introduce significant delays, during which work must continue. This is where workarounds […]

LIDAR Applications

Light detection and ranging, or LIDAR, is a type of remote sensing technology that is similar to radar. It is used in a variety of geographic and environmental applications to model and analyze the physical world. Often mounted to an airplane or motor vehicle, the sensing unit uses radio waves and the measured time delay […]

Best Practices for a Data Collection Event Using a GPS Unit

I have been a part of three different data collection efforts that collected line geometry and infrastructure of recreational trails. One effort was the development of the Fish and Wildlife Services (FWS) Trails Inventory Program. This effort involved collecting trails data in FWS national wildlife refuges across the United States. The second was an effort […]

Getting Started With the Platform Independent Model – Tools and Applications

So nearly everything we have discussed so far is not really useful unless we can figure a way to get it to help with what we need to do with geospatial data. It’s sort of like having the world’s greatest bowling ball with no lanes. How do we make this help us with increasing productivity, […]

Managing Geospatial Data Models With a PIM API

Much of the conceptual background and structure managing a geospatial data model using a platform-independent model (PIM) has been outlined in previous posts. And while it is useful to understand how the PIM is structured in the tables and views inside the PIM database, the critical knowledge relates to the way the PIM API retrieves […]

The PIM Constraint, Improving Geospatial Database Integrity

The PIM now contains sets of features (the pimFeature) grouped into sets (the pimConfiguration) with properties and referencing sets of attributes (the pimAttribute). For may GIS solutions, this is all that is required for collecting, validating, and displaying geospatial data. But the PIM also contains the ability to constrain attribute values in a variety of […]

Introduction to PIM Attributes

A quick review of the pimConfiguration to the pimFeature shows…
