About Dimension Maps:

The St. Joseph County GIS Department has prepared over 28,000 individual parcel dimension maps and made them freely available through this application.

ACCURACY:

The property dimensions on these maps are approximations derived from the county GIS parcel layer which was created to provide a general reference to the location and configuration of county parcels. They are NOT always 100% dimensionally accurate and are not intended to be. Most parcel dimensions shown on these maps are within +/- 3 ft of the actual deeded dimension. However, many dimensions may differ by +/- 10 ft or more. These dimension maps are provided for GENERAL REFERENCE ONLY. These maps are NOT a survey and not intended to be used as one. Always refer to the property deed or a survey for actual property dimensions. Consult a surveyor if you need to know the exact location of your property boundaries.

IRREGULAR BOUNDARY DIMENSIONS:

It is difficult to auto map and annotate dimensions along irregular parcel boundaries such as lakes, rivers, ditches, winding roads, etc. The dimensions along these features on these maps may be hard to read, overlapping, or incomplete. This is a known issue and the GIS Department is researching ways to overcome this limitation in the future. If you need an approximate dimension along an irregular boundary, try the interactive measuring tools in this application or similar measuring tools in the County FetchGIS online map.

SURVEYS::

The GIS Department does not provide surveying services and does not have access to any previously prepared surveys, survey markers or stakes, or any detailed property boundary information. If a previous survey was recorded at the county, it may be accessible through the St Joseph County Register of Deeds office. Local survey or title companies may also be able to assist you.

SUBDIVISION LOT DIMENSIONS:

If a parcel is located in a subdivision, the lot dimensions can be seen on the original subdivision maps available HERE.

ABOUT CONTOUR MAPS:

The St. Joseph County GIS Department has prepared over 28,000 individual parcel contour maps and made them freely available through this application.

ELEVATIONS AND CONTOURS:

The contours on these maps are derived from LIDAR data collected in 2015. Lidar (Light Detection and Ranging) is a remote sensing technology that uses laser beams to measure distances from an aircraft to the ground, buildings, and other objects. Lidar data can be used to create high-resolution 3D maps of the terrain, which are commonly used for applications such as floodplain mapping, urban planning, and natural resource management.

To create 1 ft contours using lidar, the laser beams are directed towards the ground and the reflected signals are recorded by a sensor. The resulting point cloud data can then be processed using specialized software to create a digital elevation model (DEM), which represents the elevations of the terrain as a continuous surface.

The accuracy of lidar data for creating 1 ft contours depends on several factors, including the density of the point cloud, the quality of the equipment used, and the processing techniques used to analyze the data. In general, lidar data can achieve vertical accuracy of a few centimeters or even millimeters, making it a highly accurate tool for creating detailed elevation model.
