Free GIS Viewer GeoViewer is a free GIS viewer that doesn’t skimp on features. Display raster, vector, LiDAR, WMS, and JPIP layers from one powerful viewer. GeoViewer has extensive support for industry file formats, including the industry standard MrSID format and the ISO standard JPEG 2000 format. Once you open your images in GeoViewer, you can tweak display settings for each layer to ensure that each image displays exactly the way that you want it to. Select image bands for multispectral images, adjust dynamic range settings for 16-bit images, and much more. As a bonus, you can view your imagery on a built-in OpenStreetMap base layer for context. Access Pro Features Upgrade to GeoViewer Pro to access advanced functionality. Print the layers that you open in GeoViewer, including vector layers and rasterized versions of LiDAR data. You can measure areas that you draw on the map and search for locations using addressing information. Additionally, you can change the map’s projection to more supported projections. By default, you can only view a layer in the native projection of the layer, in WGS 84, or in Web Mercator. Explore LiDAR Point Clouds GeoViewer is one of the only free GIS viewers for LiDAR point clouds. Explore LAS, LAZ, and MrSID Generation 4 (MG4) point clouds in 3-D mode or view a rasterized version of your data in 2-D mode. Customize your LiDAR experience by selecting from a long list of color gradients. GeoViewer also simplifies the process of visualizing elevation changes with an option for exaggerating elevation values, or Z values. Connect to WMS and JPIP GeoViewer’s support for WMS and JPIP servers means that you can access your data from wherever you are. When you connect to a WMS server, you can browse image catalogs from a simple interface and display them on the same map. Likewise, if you connect to the JPIP component of an Express Server, you can easily browse your JPIP layers. For other JPIP servers, you can enter the URL of the images that you want to view or select from a list of frequently accessed images. Export and Print Your Imagery Export the imagery that you display in GeoViewer. You can select custom areas to export, export the whole map, or export exactly what you see on the map. Additionally, if you purchase GeoViewer Pro, you can tile the images that you export and print your images. GeoViewer’s intuitive print interface lets you print images at full resolution or fit the images to a single page. Alternatively, you can enter the number of pages that you want and GeoViewer automatically scales your images for best fit. Try the Mobile App Want to view your imagery on the go?
