A shapefile is a simple, nontopological format for storing the geometric location and attribute information of geographic features. Geographic features in a shapefile can be represented by points, lines, or polygons (areas).
The Shapefile format is a working and interchange format promulagated by ESRI for simple vector data with attributes. An excellent white paper on the shapefile format is available from ESRI, but it is .pdf format, so you will need Adobe Acrobat to browse it. The file format actually consists of three files. XXX.shp - holds the actual vertices.
Great Lakes Shapefile. Description: A GIS format containing ice lines that separate areas of different total ice concentration, stage of development with respective ice concentrations, and ice floe size classifications. Coverage Area: Great Lakes Format: ZIP compressed, contains: SHP, DBF, SHX, PRJ, XML. Periodicity: Daily Import a GIS shapefile, or other vector dataset. GIS software, like QGIS, ESRI ArcGIS and MapInfo, have tools to export GIS data into KML format for use in Google Earth. 2020-06-09 · The Shapefile dataset format was developed by ESRI as an open GIS format, and uses as its table format for structured data a dBASE Table File (DBF) that is based on versions of dBASE format in use when the Shapefile was introduced. dBASE is a well-documented format.
Your new shapefile can then be used to depict the affected areas for each of the counties and calculate the area. Remember you are using your jpg map as a reference to create a new dataset in vector format and that is what you will use for your analysis. Tho I'm kinda new here so I'm trying to find out how things work here but I think I got something for you tho The shapefile format is a digital vector storage format for storing geometric location and associated attribute information. This format Two layers are served out: boundaries of the countries for the whole world and the geographic grid layer. These layers available at no cost to users with an ArcGIS Online subscription. dayx is the forecast day -- day1, day2, or day3; nn represents the accumulation threshold. For snow, the value will be 04, 08, or 12.For instance, a file in which nn is 04 contains the forecast probability of snowfall exceeding 4 inches.; For freezing rain, the value will always be 25, as the product depicts the probability of freezing rain accumulating more than .25 inch The shapefile format was introduced with ArcView GIS version 2 in the early 1990s.

If you load OSM data into a PostGIS database using osm2pgsql, you can use some PostGIS capable GIS software (e.g. those listed below) or run pgsql2shp (feature of PostGIS) to create a shapefile. Osmium can write all vector formats OGR supports using its OGRGeometryFactory and the gdalcpp.hpp wrapper around the GDAL/OGR library.
Geodatabases → Geodatabase format with an ArcMap map document (.mxd). (The date following each geodatabase link shows when modifications were made to the data tables and/or map document only.
A shapefile is a geospatial data format for use in geographic information system (GIS) software. For KML versions of these files, please see our Cartographic Boundary Files - KML page. For state-based and national congressional district cartographic boundary files for the 103rd through 110th Congresses, see our FTP site.
Geographic features in a shapefile can be represented by points, lines, or polygons (areas). Points, lines, or polygons can be included in a shapefile. Topographical information is not included in a .shp file which makes the file faster to process and edit.

Shapefiles The Shapefile format is a popular geospatial vector data format for geographic information system (GIS) software for storing the location, shape, and attributes of geographic features. It is developed and regulated by Esri as a (mostly) open specification for data interoperability among Esri and other GIS software products. † Dataset in shapefile format only (delivered as a .zip file) ‡ Dataset in shapefile and kml/kmz formats * Probabilistic Storm Surge is available when U.S. Hurricane Watches/Warnings are in effect ‡ • Wind Speed Probabilities (WSP) This dataset is available in shapefile and kml/kmz formats. Download Free Shapefile Maps – Shapefile is one of the most common and extensively use vector file format of GIS (Geographical Information System), developed by ESRI as an open Specification, which consist of collection of files viz.shp,.shx and.dbf extension with same prefix name.
It is stored as a set of related files and contains one feature class. Shapefiles often contain large features with a lot of associated data and historically have been used in GIS desktop applications such as ArcMap . The Shapefile is the most common format in GIS. It’s a vector format that can be read by almost all GIS systems.
