GIS Program Management

City of Baltimore, MD

Breathing Life into Public Works Data

JMT Technology Group has provided GIS program management and project management services for the expansion of the City’s Geographic Information System (GIS) for the past 12 years. JMT provides full service GIS and Information Systems support for GIS applications, asset data management and systems integration.

QA/QC of Orthophotography, Planimetric, and Topographic Data

One of JMT’s most significant achievements for the City of Baltimore has been quality assurance and quality control review of the City’s orthophotography, planimetric, topographic, street centerline and cadastral mapping updates in 2000, and the most current 2008 updates. Our quality review processes include the acceptance or rejection of deliverables from the third party vendor based on pre-determined acceptance criteria. The data is reviewed for feature capture, positional accuracy, areas of capture where change occurs, verifying topography, attribute accuracy, and quality of orthoimagery. In accomplishing this, JMT worked with the City to update and revise database schemas, update domain lists, create automated QA/AC tests, and publish metadata and detailed technical documentation.

Geodatabase Development, Management & Administration

JMT is currently managing the GIS database for Baltimore City’s Department of Public Works Bureau of Water and Wastewater. The Bureau’s database is extensive and includes base map planimetric and topographic data as well as water, storm water and wastewater utility data. Primary features of data management include coordination with other city projects collecting utility data, developing work flows for utility data editing and managing the RDBMS and SDE databases. JMT coordinates with the Baltimore City Fire Department in maintaining an accurate hydrant inventory in GIS. In addition, JMT also coordinates with external city projects collecting information on utility assets including quality control review of the data that is incorporated into the GIS database. JMT supports both the RDBMS (creating and managing export and analyze jobs, database alerts and tablespace analysis) and the SDE database (database schema modifications, reconciling and posting versions, resolving conflicts and compressing the database).

ArcGIS Server Application Development

The JMT team migrated the Bureau’s Intranet view/query mapping application known as UView from ArcIMS into ArcGIS Server. In addition, JMT developed map services to enhance and extend map content to more applications and users. Primary tasks included migrating the application code from the ArcIMS platform to the ArcGIS Server platform, optimizing the application code within the ArcGIS server platform, developing and implementing a test plan and tracking and resolving application bugs and data issues. In addition to migrating the platform of the application, enhancements and new views are included in the initial rollout and are being developed for periodic updates throughout the project.

QA/QC Data Testing Using PLTS

Using ArcGIS PLTS an automated series of QA/QC tests was created for City Stormwater data updating.  Using PLTS Data ReViewer, the QC technician will first run the automated check to make sure that the data being delivered conforms to the City standard both spatially and tabular.  The automated test looks for valid value errors, case sensitivity, domain compliance, and unique character errors. As well as geometry errors such as duplicate features, splintered polygons, and invalid feature lengths. After running the testing, the QC technician would check each flagged error to decide whether or not the flag was valid or acceptable. If invalid the error flag would be posted to an official error log for further review.

Enterprise Content Management and Systems Integration

JMT is assisting the City’s Department of Public Works in implementing an enterprise content management (ECM) and document management system using third party management software to support the ongoing operations and management of the department. Primary features of the system include document management, automated workflow, collaboration, and regulatory compliance. JMT performed a detailed requirements analysis, created a request for proposal (RFP) document that was distributed to a variety of vendors, which then led to the product evaluation process resulting in the selection of a commercial-off-the-shelf (COTS) solution that is well-suited to the department’s requirements and budget. JMT has followed up the analysis phase with system and database design, configuration, back file document importation to the system repository, and user training. Subsequent phases included workflow design and implementation and the most critical component, the integration of the document management system with the department’s web-enabled enterprise GIS application known as “UView.”
