Frequently Asked Questions:
- How much does it cost?
IMPACT is free. Registered users also get free updates.
- Who can get a copy?
Federal, state, and local government agencies may request a copy. A non-government partner can get a copy if they are sponsored by a government agency. Commercial use is not allowed.
- What operating systems are supported?
IMPACT runs on Windows, Mac OS, and Linux. It does not run natively on Android or iOS but can be used with a remote desktop app.
- How is it deployed?
Each desktop or laptop runs its own copy of the software. Windows tablets can run it natively. Android and iOS tablets can control a copy running on a desktop or laptop using a remote desktop app.
- Is a network connection required?
The software initially downloads map tiles for an area of interest chosen by the user and are stored permanently. This allows use in the field where a network connection may not be present.
- Can it run on a server?
A copy can run on a server to push static maps to a website for viewing by multiple users. IMPACT has a simple web server capability built-in. However, it can only be controlled by one user at a time using a remote desktop app.
- Do I need admin rights to install it?
You do not need admin rights on Windows to install it. Basically, you download, unzip, and create a shortcut. On Mac OS you do need admin rights to run an install script. Linux users also need root privileges to install the required packages.
- What kind of computer resources are required?
Any desktop or laptop manufactured in the last 5 years with 4GB of RAM should be sufficient. Windows tablets need 2GB of RAM. Once unzipped, IMPACT is around 5GB due to all the elevation and population files. Over time, this will expand a bit as more map tiles are downloaded.
- Can I install it on a USB drive?
Yes, but performance will be slower on flash drives compared to spinning drives due to slower write speeds.
- Will my GPS unit work with IMPACT?
GPS devices that support the NMEA 0183 standard or Garmin protocol are currently supported.
- Can I draw on the maps?
Yes. IMPACT has a number of drawing tools for adding placemarks, lines, circles, and polygons.
- What GIS data file formats are supported?
IMPACT supports a variety of GIS file formats including unprojected ESRI shape files and Google Earth KML/KMZ files. Spreadsheet data in the form of CSV text files are also supported. Geo-tagged cell phone photos can be added via drag-and-drop.
- Can I create a geofence?
Yes. With IMPACT you can create multiple circles or polygons to use as geofences and have email alerts sent whenever something enters or leaves an area.
- How do I share maps?
There are several kinds of sharing available. Entire maps can be saved and sent as images attached to an email. Individual map features can also be exported and stored on a common server. For import, IMPACT supports drag-and-drop. Map features can also be shared automatically via services like Dropbox using a built-in publish/subscribe scheme.
