GIS Division Completes Program Review


In 2020 the GIS Division conducted a review of Richland County's GIS program to establish an organizational baseline and identify priorities going into the next decade. Working with Geographic Technologies Group (GTG), the division conducted interviews with GTG personnel, recounting success stories and assessing standardized performance metrics. Evaluations also included a gap analysis, which considered the state of the County's GIS program relative to industry averages and best practices. The work culminated with the creation of a document detailing GTG's findings and documenting the current state of the program. This document has been made available online in PDF format.

Richland County Flood, October 2015


To help respond to the declared Natural Disaster in Richland County, the county GIS team has worked with numerous partners to provide recovery and assessment support.  As part of that effort, several geospatial tools have been developed and are available (below) for use by local authorities for coordination efforts and to the public for information.  We thank our corporate friends at Woolpert and Google for their support.

Flood Inundation Tool

From their Dayton, Ohio headquarters, Woolpert, Inc. flew 1 foot aerial imagery the afternoon of Tuesday, October 6, 2015 to assist in delineating the geographic extent of the flooding.  The imagery was collected over much of the City of Columbia and Forest Acres areas.  Woolpert then created a ‘Before/After’ web application to compared imagery and assess damage.  Richland County GIS provided imagery resources with assistance from Google.

RC GEO Flood Data Viewer

The Richland County GIS team assembled an online assessment tool to assist County departments in their efforts to record and analyze flooding impact.  The application is built on open source technology and includes imagery from the County’s Google contract and from flood imagery collected by Woolpert.  This tool will be an evolving application as the weeks of recovery and assessment progress.

Road and Dam Status Viewer

To assist County staff, public safety personnel, and citizens, Richland County GIS is attempting to coordinate the status of road closures/failures and dam stability.  With this objective in mind, we have published a publicly available map that is being updated by field personnel from various departments.  If you have information of your local area that is more accurate or up-to-date than this map, please email a photo of the damage, with the street name and any landmark description to: RCGEOFlood@rcgov.us  

NOTE - The Road and Dam Status Viewer is no longer available for use; Google has discontinued the use of this technology. Please see the RC GEO Flood Viewer to view our most recent information.

Automated Vehicle Location System to be Updated


Richland County has been leveraging automated vehicle location technologies to help manage its fleet of approximately 200 non-emergency vehicles since 2003 with the implementation of a home-grown VHF radio network and GPS tracking technologies.  Since then, AVL solutions have matured significantly, allowing for consumer-centric cloud hosted software as a service (SAAS) platforms to become the norm. 

Richland County is in the process of transitioning its AVL system to a new cellular based SAAS solution which utilizes inexpensive standard ODBII hardware. This will continue to provide management with the ability to monitor county assets and view historical data. Additional functionality includes both real-time vehicle activity alerts and application access from any web-accessible device. 

It is hoped that this transition will begin in the coming months and come to completion in the Fall of 2015.

The Cheese Gets Moved Again (Upcoming Changes to Some Online Mapping Apps)


The evolution of GIS and web technologies continues to move at a breakneck pace.  Every change made by large technology corporations impacts millions of users worldwide.  Technologies get developed and promoted then fall out of favor (eliminated/deprecated) for new technologies.  The most unfortunate part of that cycle is practitioners who are tasked with providing services are squeezed to support users.  Displaying mapped data online is one of those sectors that has been greatly impacted by defacto standards being superseded by new technologies.
