Maryland’s Mapping and GIS Data Portal

Maryland’s mapping and GIS “iMap” data portal takes an innovative approach to serving data.  It allows the user to zoom to a specific area on the map and then conduct a data search for that specific area.  Yes, other sites have done this for years, but the Maryland data portal uses a dynamic ArcGIS Online map to launch searches.  In addition, the 20 data categories listed–from agriculture to demographics, health to imagery, structures to weather–are rich in content, and the data user is offered numerous data formats to receive the data.  The site also goes the extra distance by providing step-by-step instructions on how to add web and WFS services, how to geocode, how to join data, and how to cartographically display results.

The GIS data portal is run by the Geographic Information Office (GIO), and by collaborating with partners, it seeks to “provide access to a large collection of data via the Maryland iMap that can be leveraged for use in many applications and analyses.”  The GIS data portal is a part of the state’s open data portal, which claims to be #1 in the USA for its commitment to open data.

We are honest in our book and in this blog about describing data portals that seem to be there “just for show” and that had no input from GIS professional staff.  The Maryland iMap portal, by contrast, is quite innovative, extensive, and GIS-user friendly, and seems to be a good model for other organizations to follow.  Such portals do not appear overnight, and this is obviously the product of a good deal of collaboration among government, private, academic, and nonprofit organizations,
