**Global Mapper** is a [geographic information system](/source/Geographic_information_system) (GIS) software package currently developed by [Blue Marble Geographics](/source/Blue_Marble_Geographics)[1] that runs on [Microsoft Windows](/source/Microsoft_Windows). The GIS software competes with [ESRI](/source/Environmental_Systems_Research_Institute), [GeoMedia](/source/GeoMedia), [Manifold System](/source/Manifold_System), and [MapInfo](/source/MapInfo_Corporation) GIS products. Global Mapper handles both vector, raster, and elevation data, and provides viewing, conversion, and other general GIS features.[2] It is most notably known for its support of over 300 different file formats ranging from .laz to [Geotiffs](/source/GeoTIFF).[3] Global Mapper has an active user community with a mailing list and online forums.[4]

## History

In 1995 the [USGS](/source/USGS) was in need of a Windows viewer for their data products, Mike Childs, intern at the time developed the dlgv32 application for viewing their DLG (Digital Line Graph) vector data products. Between 1995 and 1998 the dlgv32 application was expanded to include support for viewing other [USGS](/source/USGS) data products, including DRG (topographic maps) and DEM (digital elevation model) and SDTS-DLG and SDTS-DEM data products.[5] The development process is described in detail in the [USGS](/source/USGS) paper titled 'A Programming Exercise'.[6]

In 1998 the [USGS](/source/USGS) released the source code for **dlgv32 v3.7** to the public domain. In 2001, the source code for **dlgv32** was further developed by Mike into the commercial product **dlgv32 Pro v4.0** and offered for sale via the internet. Later that same year the product was renamed to **[Global Mapper](http://www.geonet.co.id/)** and become a commercial product of the company Global Mapper Software LLC.[7] Mike capitalized on this opportunity and acted as the salesperson[,](https://globalmapper.id) developer and tech support for almost a decade. [8]

On November 2, 2011 [Blue Marble Geographics](/source/Blue_Marble_Geographics), at the annual user conference, announced they had purchased Global Mapper LLC.[9] Mike Childs joined Blue Marble Geographics after the sale, and remains a key developer and guru of the software.

## Releases

Since the initial commercialization of the Global Mapper product in 2001, there have been yearly major product releases and numerous intermediate point releases adding additional functionality to the software.

A mobile version of Global Mapper, Global Mapper Mobile, was released in 2016.[10]
