A  specific  factor  that  has  separated  this  technology  from  other ystems  of  reserve  and  information  recovery, is  outlook  manner  of  it  to  geographical  areas. GIS  with  this  specification  as  a  modern  technology, has  been  changed  to  an  industry  searching  in  analysis  of  quantitative  and  qualitative  data  and  designing    the  kinds  of  geographical  pictures.

Geographical  survey  of  Iran, considering   increasingly  developments  of  science  about  GIS, established  the  group  of  ground    information  of  source  in  ground  sciences  branch  specially  in  mineral  exploration  in  the  world  with  a  systematic  set  from  expert  powers, modern  equipment  and  spatial  data  by  geometrics  management  from  1375.

 Collection,classification,digitization of spatial and descriptive data and formation of involved data bank. Management of data with high capacity and provision of necessary standards. Management of data with different sources

and preparing  required outputs.

 Combination of different raster and vector data and preparing   thematic maps .Preventing repetitions resulting from unawareness of groups and the other users about former works. Preparing maps of mineral prospect areas by arrangement based on genesis and recovery model and analysis of various data including geological data, geochemical data , airborne geophysics ,remote sensing and recognized mineral areas. Preparing natural hazard maps that related to slope stability,  landslide, zonation of damage landslides, erosion and … .Cooperation to prepare involved national and international maps.

  
Performance of joint projects with domestic and foreign companies

 Selection of proper locations for accomplishment of engineering projects like dam construction, repelling  excessive materials,tunnels,…the group object for using GIS, is usually preparing  mineral potential maps .Geological analysis in a region whether for mineral exploration or for oil exploration and so on is basically a combined process of various data. A geologist or explorer can find the objects of this project by relating various data of geology. All geological data for being useful,should be analyzed based on geographic position .GIS by demonstration and analysis of various data enables the involved expert to provide maps that have mineral potential with different data ,although this is impossible by traditional and analogue methods .For mineral prospect is required to collect different layers of data such as geological maps, airborne geophysics data ,remote sensing data, geochemical exploration information and recognized mineral information that will be introduced during special survey correspond to modern methods and modeling and limits as having potential priorities .In past ,choice, evaluation and information combination and existing evidences for recognition of mineral points ,was done by a light desk, various maps were overlaid each other physically to determine joint relations among anomalies. GIS developed this process increasingly and increased required facilities for special data process and analysis of spatial data according to common patterns of the world .

Some accomplished works in this group included :

Presenting mineral prospect areas on scale of 1:100.000,1:250000 in provinces of West Azarbijan,Kordestan, Yazd ,Kerman,Mazandaran.Preparing digital geological maps , engineering geology ,mineral distribution, geomorphology, met alogeny,…  on different scales. Digitization of seismo-tectonic d map of the world by order of geological maps commission and UNESCO .Translating  geographic informational systems book for Earth science researchers. Preparing zonation maps of landslide risk in Central Alborz ,Semnan province, Takhtesolayman .Finding a place for  litter burial in Sari. Provision of thematic reports about gold and antimony. Preparing  geomorphologic digital map of Takhtesolayman (1.100.000).Airborne geophysics section was separated from GIS group as a free group at the beginning of 1382.
