Impervious Surface Calculation Products

Sanborn offers four Impervious Surface Mapping Products, with two primary data generation approaches, all designed to provide the baseline data needed to meet any impervious surface mapping challenge. Our products have been proven effective for planning and land management applications in communities across the United States.

STANDARD IMPERVIOUS

The Standard Impervious Surface Mapping Product is generated from 2.5m orthoimagery and classifies surfaces into impervious or pervious categories with accuracies of 90%. The Standard product does not identify specific types of impervious surfaces. This product is a raster product and should not be converted to a vector environment as the datasets will show pixelated edges.

Sample: Standard Impervious Surface Mapping Product draped over 2.5m resolution orthoimagery – Maui, Hawaii

Standard Impervious Surface Mapping Product

ENHANCED IMPERVIOUS

The Enhanced Impervious Surface Mapping Product is generated from 1.0m orthoimagery. The Enhanced Product uses higher pixel resolution imagery than the Standard product, and classifies areas into impervious or pervious categories than the Standard product, with accuracies of 90%. The Enhanced product does not identify specific types of impervious surfaces. This is a more economically-priced product than the Planimetric and Premium products.

Sample:Enhanced Impervious Surface Mapping Product over 1.0m resolution orthoimagery – State of Delaware

Enhanced Impervious Surface Mapping Product

PREMIUM IMPERVIOUS

The Premium Impervious Surface Mapping Product is generated from 1′-6″ orthoimagery and is more accurate for identifying smaller impervious features than the Standard and Enhanced products. The Enhanced Impervious Product classifies features into impervious or pervious categories with accuracies of 95%, but does not identify specific types of impervious surfaces. The data will exhibit pixelated edges, but they’ll be much less noticeable when compared to the Standard / Enhanced products.

Sample: Premium Impervious Surface Mapping Product over 6” resolution orthoimagery – Ann Arbor, Michigan

Premium Impervious Surface Mapping Product

PLANIMETRIC IMPERVIOUS

The Planimetric Impervious Surface Mapping Product is generated from 1′-6″ ortho imagery, and employs a vector dataset to identify varying impervious surface types with accuracies of 99%. Vector-based boundaries generated by this product are generally straight lines.

Sample: Planimetric Impervious Surface Mapping Product draped over 1′ resolution true color orthoimagery and heads-up compiled planimetrics – City of Bellevue, Washington
