The three files required have the extension. You can convert a Shapefile map into a GeoJSON map using this tool as follows: Select GeoJSON to convert the Shapefile map to this format, and then click on Export. Click on Export to save the map in various formats. They will usually not be very visible, unless you zoom into the map. Usually mapshaper can fix them, but if not, you can just choose to leave them in. Make sure to also click on repair in the top-left corner if intersections are detected (caused by simplified adjacent geometric shapes). The percentage simplification indicates how much the file size will be reduced. Simplify the map by moving the slider to the right. Make sure to select prevent shape removal as shown in the image below, otherwise map areas may disappear through the simplification process! Then, click on Apply. You can now export directly (see Step 5 below) or simplify the map by clicking on Simplify in the top-right menu. The map should open as in the example below. prj file (projection format, if you are using a particular map projection). shx file (shape index, a positional index of the individual shapes / features), and the. Two other files which are commonly included are the.

These are the only two files required by StatPlanet to create interactive maps. dbf file (which contains the map attributes, linking the map IDs and names to the corresponding polygons). shp file (which contains the map shapes or geometry), and the. To select multiple files, hold the CTRL button while selecting the files.Ī note about shapefile map files:The two most important files are the. shp files (see below), and if available, also the. Your shapefile map consists of several files. Open, and click on select to attach your map files. (See also, converting a map using ogr2ogr). Map simplification is great for online map visualizations, since it can reduce the file size to less than 10% of the original. The first tool is, which is the recommended tool as you can also 'simplify' the map at the same time, reducing the file size.

#Arcgis file structure software#
Geodatabase software logic provides the common application logic used throughout ArcGIS for accessing and working with all geographic data in a variety of files and formats.In addition, advanced GIS data objects add real world behavior rules for managing spatial integrity and tools for working with spatial relationships of the core features and attributes.
#Arcgis file structure series#
This information model is implemented as a series of tables holding feature classes and attributes. Geodatabases have a comprehensive information model for representing and managing geographic information.You can access and work with this physical instance of your collection of datasets either through ArcGIS or through a database management system using SQL. It is the physical store of geographic information, primarily using a database management system or file system.While ArcGIS works with geographic information in numerous geographic information system (GIS) file formats, it is designed to work with and leverage the capabilities of the geodatabase. The geodatabase is the native data structure for ArcGIS and is the primary data format used for editing and data management.The term geodatabase has the following meanings in ArcGIS: Geodatabases come in many sizes have varying numbers of users and can scale from small, single-user databases built on files up to larger workgroup, department, and enterprise geodatabases accessed by many users.īut a geodatabase is more than a collection of datasets. At its most basic level, an ArcGIS geodatabase is a collection of geographic datasets of various types held in a common file system folder, or a multiuser relational database management system such as IBM Db2, Microsoft SQL Server, Oracle, PostgreSQL, or SAP HANA.
