![]() ![]() In 2019, Google revealed that Google Earth now covers more than 97 percent of the world, and has captured 10 million miles of Street View imagery. Google Earth is able to show various kinds of images overlaid on the surface of the Earth and is also a Web Map Service client. Users may use the program to add their own data using Keyhole Markup Language and upload them through various sources, such as forums or blogs. The program can also be downloaded on a smartphone or tablet, using a touch screen or stylus to navigate. Users can explore the globe by entering addresses and coordinates, or by using a keyboard or mouse. The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles. Google Earth is a computer program that renders a 3D representation of Earth based primarily on satellite imagery. Linux ( Ubuntu 14/ Fedora 23-equivalent or later).Regardless of what piqued your interest in finding up-to-date satellite imagery in the first place… I hope you find what you’re looking for. If you decide you’re going to pay for imagery, do your own homework some of the best deals you find are from independent pilots who will fly aerial or drone imagery for you on an hourly basis! ![]() Last time I checked, there were over 20 different browsers for looking at Landsat 8 imagery alone and that was more than three years ago! There are also plenty more aerial and satellite imagery providers-I simply listed some of the largest ones. There are plenty of other places to get access to some of the datasets I mentioned above-especially the free ones. If you’re new to this world, the first thing to know is that you’re almost certainly going to have to speak with a salesperson-there’s no such thing as simple, transparent pricing in the satellite and aerial imagery world (at least not yet).įor slightly lower resolution but higher frequency imagery:įor aerial imagery in the U.S. We run into this situation quite frequently at Azavea, so we’ve gotten to know many of the providers over the years. Lastly, there’s the difficult case of needing high resolution, recently collected imagery (especially if you plan to derive commercial works from that imagery and need access to the raw files). That imagery can also be downloaded from either Earth on AWS or the Earth Engine Catalog-you can also browse when the most recent imagery was collected for each state (and at what resolution) at this free online coverage map hosted by ESRI. In the U.S., the USDA’s National Agricultural Imagery Program (NAIP) captures 1m/pixel or better imagery for the entire contiguous United States once every other year. Make sure you familiarize yourself with the data before downloading a lot of it!įor high-resolution aerial imagery, your options are much more limited. A warning: these are very large files and the imagery itself is lower resolution than what you might expect to see on a typical web map.
