Impervious Surface Maps

eMap International produces standard Impervious Surface Map (ISM™) products designed to meet the multiple requirements for NPDES1 compliance and management of Stormwater runoff. These ISM™ products are delivered to clients more quickly, affordably and accurately than previously possible while accommodating different project sizes - from towns and municipalities, to counties, regional districts and watershed systems.

In response to the needs of the Stormwater Management community, eMap has pioneered the use of remote sensing image processing to produce impervious surface layers for different geographic and ecological regions. eMap employs an all-digital solution using advanced Earth-imaging technology and innovative data processing techniques to produce superior ISM™ products.
