High resolution files for large areas (countries) can be very large. A cell with a 30 seconds resolution is about 0.8 km2 at the equator and smaller at higher latitudes. The size in square meters varies with latitude. ![]() When the cell size is small (e.g., 30 seconds), resolution is high. Anti-Beacon allows you to put an end to it. The units are in (arc) degrees, minutes or seconds. Unknown to you Windows and third party software is constantly collecting and transmitting data from your computer. ![]() The resolution is the size of each grid cell expressed as the length of one side of one (square) cell. For the other gridfiles, NODATA is only used for areas covered with water, except for the land cover grids, on which water is a separate class.Ī DBF (dBase file) is a dbase format database table. For these areas, the value is "NODATA" (indicating the absence of data for those cells). ( More info on format for developers).Ī gridfile with "country mask" indicates that the areas outside the selected country are masked out. From DIVA-GIS they can be exported to a number of other grid formats including IDRISI and Arc or to shapefiles. Shapefiles contain a single class of "vector" data such as points, lines, or polygons. It can be imported to most other GIS programs. This is a commonly used format that can be directly used in Arc-anything, DIVA-GIS, and many other programs. Grid (raster) data are stored as DIVA gridfilesĮach "shapefile" consist of at least three actual files. Vector data are stored as ESRI shapefiles You can use programs such as 7-zip, PKZIP or StuffIt to decompress the files. The files have been compressed and grouped in ZIP files. National Imagery and Mapping Agency's (NIMA) database of foreign geographic feature names They can also be used to map localities, however you can download more recent files from NIMA The files should be placed in the \gazet directory. The files you can download here are for use in DIVA for automatic georeferencing (to assign coordinates to places). Global gridded population databaseĪ gazetteer is a list of place names and their coordinates. Land cover, original data resampled onto a 30 seconds gridĬIESIN, 2000.

G Data CloseGap active hybrid protection detects and closes holes in the protective shield fully automatically. However, the double detection uses up a lot of computing resources. However, G Data CloseGap offers one other advantage over the dual engine concept used to date: the use of resources is significantly lower.Ī dual engine provides perfect protection against online threats. This means that your data is ideally protected all the time – even in the event of new, previously unknown attack scenarios. ![]() CloseGap receives additional enhancements with every update, so the functionality can easily be adapted to the current threat. G Data CloseGap technology takes a different route, combining proactive, signature-based security technologies in powerful active hybrid protection. Traditional antivirus solutions frequently cannot keep pace. A short response time between the first occurrence of the malware and the availability of a corresponding virus signature is often essential. Precision and speed are critical for the fast, successful avoidance of computer malware. ![]() Active hybrid protection for fending off malware and online attacks
