Planimetric data in Riverside

Help_Planimetric_data_in_Riverside.jpgPlanimetric ​data are geographic features captured during a
photogrammetric (airplane fight) mapping process that are flat and
without elevation information to depict the terrain. Such features
include bridges, roadways, building footprints, bodies of water, and
railroad lines. Photogrammetry is the most cost-effective method for
producing this type of mapping information for large areas and these
features typically represent the base data in a map. As a member of the
GIS Consortium the Village of Riverside participates in an annual data
collection process which allows them to obtain such planimetric data.
An advantage for the community is that they receive cost savings being a
part of such a large group contracting these services. The current
service provider for photogrammetric mapping is Ayres and Associates of
Madison, WI.

There is a processing and review procedure for the data to be sure it
meets the accuracy standards that have been established by the GIS
Consortium. Generally, all planimetric features will be within 1.67’ of
their actual field location if collected under the traditional
Consortium standards. On occasion the data collection has had to
deviate from those standards due to circumstances outside of a village’s
control such as experienced by Elk Grove Village due to its proximity
to O’Hare International Airport and the flight restrictions they have
over and around the village. The data collection in Riverside has not
been affected by any circumstances and therefore meets the GIS
Consortium standards.

In the spring of 2008 and 2009 data was collected for the Village of
Riverside. Planimetric features for the South half of the community
were delivered, reviewed, and integrated into the GIS (Geographic
Information System) in the fall of 2008 and the North half of the
community in the fall of 2009. You may have noticed this data in the
MapOffice™ interactive mapping application
http://www.mgpinc.com/MapOffice™/.

As mentioned above, this data is usually used to compose a map
presentation, but also provides for impervious surface estimations,
GASB34 statistics, routing, cost estimates for replacement or removal of
infrastructure, and preliminary design or planning.
