Free gi data software

It's capable of base map import and features a drag-and-drop interface, editing tools, and vector operations. This open-source platform works as an independent application or as an extension of other RCP plugins. Compared to other options here, the uDig community is smaller, meaning updates are less common. There you have it! Our top eight picks for the best available free GIS software.

Get started in GIS and mapping by downloading a day free trial. New to GIS? Conclusion There you have it! Intimidated by GIS? It provides two separate View and Tables options on the side panel to view Maps and Attributes, respectively. In its view section, you can load SHP files containing the geographical map.

To take a closer look at geographical maps, you can use available tools like zoom in , zoom out , pan east , pan south , etc. As soon as you load a database file, you can immediately view all GIS attributes on the interface. Plus, options to create , update , and save individual attributes as dbase file are also present in it. This software also offers some advanced tools namely Statistics to extract important statistics like variance, standard deviation, mean, etc. However, this software only shows the spatial geographic data and not the attributes of geography.

This tool highlights all the boundaries contained in the spatial map or data. Some smart features like the ability to pan the map by holding the right click and option to highlight the boundary region of selected shape are also present in it. Using it, you can view all the GIS information contained in a shapefile. It also helps you study and analyze borders of various countries , states , or any other region in details. While viewing the shapefile, you can use zoom in , zoom out , or pan tool to analyze region boundaries and shapes clearly.

This software comes with its own file explorer through which you can browse and load SHP files. However, you can create shapefile shape index format.

GIS data might be in different format, might be in shapefile or other software format. Mostly GIS Data viewer are light weight software which has limited functionality and are perfect for browsing data. Arcgis Explorer Desktop. It also allows you to explore, visualize, and share GIS information. ArcGIS Explorer allows you to access free base maps and GIS layers from ArcGIS Online, fuse your local data with online data, allows to add photos, videos and other documents with your map, perform spatial analysis like visibility, modeling, and proximity search.

Click here to download. ArcReader is a free GIS viewer, easy to use desktop mapping system that allows users to view, explore, and print maps.

With ArcReader you can view, zoom, print, navigate and create custom ArcReader application. It comes with a user-friendly interface and supports both vector and raster file types. All the layers added to the project are easily accessible in the Maps tab on the left panel of the software.

It lets you import shapefiles as various layers from your PC. You can view the properties of each layer.

You can arrange the added layers horizontally or vertically. Moreover, any layer can be shown or hidden by right-clicking on it. You can also vary the transparency of a layer which is set to zero by default, turn it into grayscale, invert its colors, etc. Do note that SAGA cannot handle multiple bands imagery. This means that viewing different shapes and the land covers is not possible on one band at a time. For this, you have to create a false color composite.

A false color composite must be created as a separate image or must overwrite a previous image. This free GIS software also creates a histogram of a band. A histogram is basically a frequency distribution, in which band statistical data such as water vegetation, dry soil , etc. We can use the histogram only for a single band. If there are more than one bands, we have to use Scatterplot. You can zoom into or out of a histogram. As you zoom into a histogram of a selected band, the respective area on the band also gets zoomed.

The histogram also shows the arithmetic mean and standard deviation of the band. You can view these details in the description tab. It also has a measurement tool by which you can measure the distance between any two points on the map. Some of its great features include: Simulation, Cartographic projections and georeferencing, A number of raster and vector data tools, Image processing, Terrain analysis, Geostatistics, Map view, Notifications, and many more.

It is a free GIS software for Windows which lets you manage and analyze the geographical data. You can create multiple layers blank or import shapefiles in your project, mark multiple points at different locations on a map and name them, create paths among points, etc.

After creating your own maps, you can publish them on the internet. The good part of the software is that you can process both vector and raster files in it.

You can change the properties of layers point layer, line layer , etc. For example, if you want to highlight airports, restaurants, schools, etc. Moreover, you can also change the coordinates of points and label them. See the above screenshot in which, I selected the Madagascar island, marked its boundaries, and created my own map by creating a path between any two points, say Beach and Treasure.

I also added a point layer on which I highlighted some airports and also labeled them. In this way, you can add more details to your map by creating multiple shape layers in your project. Apart from the above-listed features, a measurement tool is provided by which you can take the following measurements:.

Annotation is another good feature of this software. Five types of annotation tools are available, namely, text annotation, form annotation, HTML annotation, SVG annotation, and move annotation. After completing your project, you can save it in QGS format.
