Throughout time maps has lead travelers along the may routes through the wilderness.
Without maps how would you know where you are?
When maps became accessible on your mobile phone or GPS unit. Taking maps mobile was just another step. Now we hsve a flood of different GPS units, Mobile Apps all competing for your time, money. Thanks to QGIS and free data, you can create your own georeferenced maps! Although learning how may take a year or so.
Where can I buy maps?
You can by one already built here, or you can build one using our request page. You can also find many common maps online both free and paid for. What I'm offerning here are maps less common and may not exist anywhere else.
PDF (Portable Document Format) is a file format that has captured all the elements of a printed document as an electronic image that you can view, navigate, print! PDF files are created using Adobe Acrobat, Acrobat Capture, or similar products. GeoPDF maps are standard PDF file format but with projection information included within the document. This allows programs that can read this information to place the document within a spacial plan on your device. Basically placing the map where you are in the world by using GPS satellites to find your location. GeoPDF files can be read by standard PDF viewers and printed.
TIFF (Tag Image File Format) is a common format for exchanging raster graphics (bitmap) images between application programs, including those used for scanner images. A TIFF file can be identified as a file with a ".tiff" or ".tif" file name suffix. GeoTIFF maps are standard TIFF file format but with projection information included within the document. This allows programs that can read this information to place the document within a spacial plan on your device. Basically placing the map where you are in the world by using GPS satellites to find your location. GeoPDF files can be read by standard PDF viewers and printed..
JPEG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG can also be georeferenced by adding two files, both are used to georeference the image in different programs. Althrogh the file size can be smaller, the quilty of the image degrads if scaled up and is less desireble then PDF or TIFF's file formats.
What is NAIP?
The National Agriculture Imagery Program (NAIP) acquires aerial imagery during the agricultural growing seasons in the continental U.S. A primary goal of the NAIP program is to make digital ortho photography available to governmental agencies and the public within a year of acquisition. NAIP is administered by the USDA's Farm Service Agency (FSA) through the Aerial Photography Field Office in Salt Lake City. This "leaf-on" imagery is used as a base layer for GIS programs in FSA's County Service Centers, and is used to maintain the Common Land Unit (CLU) boundaries.
This map is intended to depict physical features as they generally appear on the ground and may not be used to determine title, ownership, legal boundaries, legal jurisdiction, including jurisdiction over roads and trails, or access restrictions that may be in place on either public or private land. Obtain permission before entering private lands, and check with appropriate local government offices for restrictions that may apply to public lands. Lands, roads and trails within the boundaries of the this map may be subject to restrictions on motor vehicle use. Obtain a Motor Vehicle Use Map, or inquire at local government offices for motor vehicle access information. Natural hazards may or may not be depicted on the map, and land users should exercise due caution. This map is not suitable for navigational use.
