Images digitalglobe terms of use map satellite. Three Key Focus Areas for DigitalGlobe: Space, Maps and Access
“The CTO of DigitalGlobe once said that we should have all of our satellite data in the cloud by 2014, and many were bewildered by this. All these years it has been about avoiding clouds in our satellite imagery, ”says Pierre Izard, Senior Director of Strategy and Nate Ricklin, Director of Platform Development at DigitalGlobe.
A little over a year ago, thanks to our collaboration with our AWS partners, everything became a reality. AWS Snowmobile (a 13.7 m shipping container with special shielding, transported by a truck with a trailer) delivered exabyte capacity to the company's headquarters in Colorado, and the entire 18-year-old DigitalGlobe imaging library was moved to the most dynamic and the world's most technologically advanced cloud infrastructure. In November 2017, it was announced that all of our data was already on AWS, and work began. The company has moved to where the majority of its users work. No more time wasted developing technologies that can be obtained from AWS. The company is focused on serving its customers. The CTO was right.
On the occasion of the AWS Annual Summit, it is appropriate to provide a brief summary of what has been accomplished since the 100 petabytes of data from the DigitalGlobe constellation moved to the cloud.
The company is engaged in solving undifferentiated time-consuming geospatial problems. And depending on the client, this can mean a lot of different things. And to understand this, let's focus on three areas - SPACE, MAPS and ACCESS, and provide more information about what is happening in DigitalGlobe:
SPACE
- DigitalGlobe performs a significant number of operational tasks within its framework of goals. Hundreds of surveying operations per day, 70 terabytes of satellite data every day, all this provides quality service to key partners and customers around the world.
- DigitalGlobe is bringing all imaging processes to the cloud using the cloud-based ground infrastructure architecture deployed to support the 2016 WorldView-4 mission.
- This quarter, DigitalGlobe activated the fire channel, placing images in a cloud-optimized format for faster access and use, taking advantage of the scalability of the new architecture to efficiently support post-processing, operations and distribution environments. By the end of the year, all images of the constellation will be fed through the fire channel, significantly shortening the time frame for receiving applications and eliminating the need to “process orders” that must be in the ground segment of the mission. Given the growing volumes of data and the computation required, the company's old data center structure would not have been able to handle this.

CARDS
- The amount of data flowing through the fire channel is in many cases frightening for customers. Few are pushing for hundreds of terabytes of pixels to support their own maps. Product managers, visualization specialists and development teams software Leverage the cloud and the power of computing and storage to create ready-to-use content tailored to diverse scenarios and user challenges.
- Algorithmic mosaic solutions produce highly accurate, ultra-high resolution, tonally balanced, consistent geospatial data across a continent to support DigitalGlobe's custom platforms and subscription products. These access technologies provide SecureWatch and GBDX services to DigitalGlobe content users, as well as data supplied by DigitalGlobe partners that are stored as a source of information in the content management segment, for example, images from the RADARSAT-2 radar satellite, KOMPSAT satellites, elevation data and ground control points. from various vendors, as well as many open source channels from ESA, NASA and NOAA.
- Sometimes the least visible things are the most important. Imagine if Netflix didn't know who owns the rights to Star Trek, what legal problem would it have if they started streaming these episodes without licensing controls? The same battle for proper data licensing is taking place in the geospatial realm. As the amount of data processed increases, DigitalGlobe maintains robust discovery, management, and control capabilities. The company relies heavily on AWS technologies such as Amazon S3, Amazon Glacier, and Amazon SageMaker for lifecycle, security, cataloging, and business content delivery.

ACCESS
- Many users are in need of more discrete and interactive interfaces and are looking to support access solutions that provide highly flexible and iterative cloud experiences.
- Launched in May 2018, GBDX laptops and ever-expanding online content subscription products such as SecureWatch and the Maps API support interactive workflows that require a company to support automated scalable systems in anticipation of spikes in global usage.
- In the context of GBDX, cloud operations allow developers to test their scientific data codes in selected areas for evaluation and validation. They can then easily set goals for further content filling at a higher level than otherwise possible.
So, we have come close to the most interesting thing: viewing and selection of archival satellite material. Based on the results of this process, we will either find the images we are interested in and determine the cost of the order, or make sure that we have to order a new survey.
As shown in Chapter 6, we are only interested in satellites with a resolution of 0.6 m and higher. Today there are four such satellites:
DigitalGlobe:
. QuickBird(color 0.6 m)
. WoldView-1(b / w 0.5 m)
. WoldView-2(color 0.5 m)
GeoEye:
. GeoEye-1(color 0.4 m)
Currently, there are already many web services that allow online searching for archived satellite images by polygons of specified areas.
The main drawback of the SovZond service is the inability to load the image search area from a shapefile. Its main advantages are open links to the images pages, from where you can download a high-quality quicklook "and the ability to download all the shapes of the selected images at once.
The "native" service DigitalGlobe unfortunately does not accept files in UTM projection (only in geographic coordinate system) and has a creepy interface.
DigitalGlobe has updated its basemap guidelines. Now the minimum use case starts not with a free subscription, but with $ 5 per month, see here: https://platform.digitalglobe.com/maps-api/pricing/.
Users of ArcGIS Desktop, ArcGIS Pro, ArcGIS Server, Portal for ArcGIS, ArcGIS Online can use Esri basemaps, which contain satellite imagery, feature data, and other thematic datasets.
Let's figure out how to connect additional sources base maps and do it using the example of space survey. It is clear that users want to see the most relevant imagery at high spatial resolution. The solution may be to share multiple data sources. Esri basemaps are connected by default. Additionally, connectivity to BingMaps and imagery is described in the ArcGIS Help.
DigitalGlobe can become a new source of space images, with the help of it, for some regions of our country, it is possible to increase the relevance of space images and their spatial resolution in comparison with the data available from Esri. The connection can be made for both ArcGIS desktop clients and the web. There is a coverage map for DigitalGlobe imagery, both by year of shooting and by resolution. Unfortunately, DigitalGlobe does not provide the exact date of shooting in its services. A little comparative analysis showed that, in general, DigitalGlobe images are of higher resolution and more relevant, although not everywhere.
To connect to DigitalGlobe services, you will need to create an account. Please note that free connection is possible with certain restrictions, read more about the terms here: https://developer.digitalglobe.com/maps-api/ in the Maps API Pricing section.
After receiving your account, you will be provided with a unique key - API key on the page http://mapsapi.digitalglobe.com/account
In addition to the API key, you will need a unique Map ID, the options are presented in the table below. The most interesting product is "Recent Imagery".
Recent Imagery | digitalglobe.nal0g75k |
Street map | digitalglobe.nako6329 |
Terrain Map | digitalglobe.nako1fhg |
Transparent Vectors | digitalglobe.nakolk5j |
Recent Imagery with Streets | digitalglobe.nal0mpda |
To connect the service to ArcGIS Online, ArcGIS Pro, Portal for ArcGIS in the map viewer, click Add - Add Layer from Internet, select the data type Tile Layers and enter the link: https: // (subdomain) .tiles.mapbox.com /v4/map.id/(level)/(col)/(row).png?access_token=your-api-key. In this link, you must replace: (subdomain) with a or b or c, map.id with the number in the table above, your-api-key with the received key, i.e. for example, the link will be: https://a.tiles.mapbox.com/v4/digitalglobe.nal0g75k/(level)/(col)/(row).png?access_token=api_key. Check the box to make this map baseline.
The picture shows the village of Bolshiye Tigany in Tatarstan. There are almost no houses on its map: unsurprisingly, there are no Bing imagery or Mapbox imagery. But now we can cover them using the background in the illustration. Kevin Bullock kept the promise we discussed.
Yesterday, there were two new satellite layers in the three main editors. In JOSM, you need to go to the snapshot settings, select two lines with "DigitalGlobe" and click "Activate". In iD press the button with layers on the right, in P2 - on the button "Matte" at the top. The layers are:
- DigitalGlobe Standard: 30-60 cm resolution, covers 86% of the land area, more every year. Updated twice a year in the USA, Western Europe and Australia, every two to five years in other regions. In Moscow, for example, it is surprisingly old: from about 2013, in other places it is fresher than the rest. Similar to the "Recent Imagery" layer available to DG Maps API users.
- DigitalGlobe Premium: Similar to the "Premium Imagery" or "+ Vivid" layer available only to DG corporate subscribers. It has slightly more high-quality images, but many are older than the alternatives. They write that the layer is updated more often, especially in special regions, such as Helsinki. There are no such special regions in Russia. Very often there is no difference between this layer and Mapbox: the same winter images and no oversize.
For the time being, we determine the freshness of the pictures by eye. Kevin writes that in a couple of weeks metadata will be added to the layers with the dates of photography and publication. For now, you can use the freshness map for Standard and Premium (turn on the “Mapbox” checkbox in the upper right). It's hard to trust them, given the apparent difference between the layers, but the map as a whole by the absence of rectangles in 2016 color reflects the impression of the layers. DigitalGlobe also publishes quarterly surface survey plans.
The snapping accuracy floats. The Standard layer is roughly analogous to Bing with its distortion in mountainous areas. However, St. Petersburg is flat as a table, and distortions are present there as well. Premium, like Mapbox, is better tied. Connect the track layer and use the offset base. Officially, the layers have an accuracy of 10 meters according to CE90: for 90% of measurements, the deviation will be within ten meters.
The DigitalGlobe Underlays Terms of Use explicitly permit rendering for OpenStreetMap and only for it. Pictures cannot be downloaded and used for other purposes. DG is not responsible for broken eyes and shattered foreheads from facepalms when evaluating the quality of the substrates. The same page mentions a similar permission from Mapbox, which includes an astonishing limitation: “If you are a Premium plan, you can also sketch our images for commercial purposes, but no more than 100 points, lines or polygons. in year».
Discussing new layers on the forum. They first rejoice at underlays, then frustratedly find that they either duplicate Bing or Mapbox, or are unbearably old. The new images closed many holes and supplemented the hard-to-read winter images with summer ones: they mention the Saratov and Ulyanovsk regions, Mordovia and other regions. Kevin asks to remember that new images are added all the time, with big quarterly updates like Bing. Claims and requests write in his subject in English.
