ESRI ArcGIS ( Arc – GIS ) shapefiles would be the industry standard and use nearly all GIS programs including ESRI ArcView, ArcExplorer, ArcGIS, and Maptitude, Mapinfo, Manifold, Mapwindow, Mapguide along with other free and open source applications. Each shapefile set includes: roads, structures, natural features, places, sights, railways, and waterways.
If you’re a new comer to GIS and shapefiles and wish to understand more about cartography and digital geography, take a look brief introduction. Also, you should use our free Learn2Map GIS Tutorial & Atlas and incorporated free software application to produce your personal GIS projects viewing and mixing these along with other free ArcGIS shapefiles.
Global Aerosol from Earth Observation (GlobAerosol)
The GlobAEROSOL generates daily global aerosol maps for that period 1995-2007 by merging ATSR-2, AATSR, MERIS and SEVIRI satellite data. These products created are aerosol optical depths at .55 and .87um and Angstrom coefficient and believed speciation.
This dataset comprises the next product types:
ATSR-2 Orbit-based Pixel Counts. They are extra files generated for ATSR-2 alone, that have the amount of instrument pixels from each funnel that have been incorporated in every retrieval grid cell. Individual-sensor Orbit-based Aerosol Products (IOAP). These files contain all of the output of the baby sensor retrievals, with coverage akin to those of the initial level 1 (radiance) data in the sensor.
Individual-sensor Global Aerosol Products (IGAP). These constitute bias-remedied daily maps of aerosol qualities produced from each sensor, in a specific time. For ORAC retrievals answers are only reported for that “best” aerosol type (which type is identified). In every case the IGAPs contain estimates of aerosol optical depth (AOD) at 550 nm and 865 nm and also the Angstrom coefficient.
Merged Global Aerosol Products (MGAP). One MGAP is produce each day which mixes the outcomes all available sensors right into a single map within the same format because the IGAPs, valid for the similar specific time. Exactly the same formula is determined below to apply the merging steps essential to generate both IGAPs and MGAPs in the IOAPs. In the processing perspective IGAPs are created by running the merging plan using IOAPs in one instrument only.
Record products. These composite goods are calculated in the previous IGAP or MGAP files more than a certain period (i.e. days, several weeks or years).
All goods are based on the NetCDF format, a piece of equipment-independent, self-describing, binary data format standard for that exchange of scientific data. The particular information on the format and items in these files are available in the GlobAEROSOL Product User Guide (PUG).
