The Esri 2016 User Conference has drawn to a close, but what a wonderful, action packed week it was. I was fortunate to meet a lot of you when you stopped by the imagery island in the showcase, and heard many compliments for the team on the webinars we put on over the last year. The UC always has so many sessions and great things to do, that it is impossible to catch everything. So here is a recap of my favorite plenary sessions that demonstrate using ArcGIS imagery technology to solve various problems you may be encountering today. Imagery and Drones | Esri Video -- Esri imagery product manager Peter Becker talking about multiple topics including: the New Polar Landsat services available through ArcGIS Online; New Classification tools in ArcGIS Pro, and the New Drone2Map app. This video opens with a great imagery video narrated by Lauren Bennett. Kalmar County Museum | Esri Video -- Kalmar County Museum archaeologists demonstrate how they are using imagery and ArcGIS imagery capabilities to uncover details that were buried long ago. The Living Atlas | Esri Video -- Esri's Deane Kensok discusses content in the Living Atlas from Esri, and our customers and partners. He also discusses updates to the World Imagery basemap. You should have also received the new ArcGIS Imagery Book in your conference materials. Don't forget to visit the companion electronic website, which includes all the learn lessons and over 150 links to gorgeous imagery, videos, storymaps and more. Thanks for reading, and it was great seeing you again this year at UC!

Landsat Polar image services. Intrigued, I opened my email the other day, and was treated to some of the most gorgeous imagery of the Arctic and Antarctic I had ever seen. Not only did the email contain the images you’ll see in this blog, but also links to two new applications I could use to explore the imagery in the regions and easily share it with others. Let me give you an overview of the two new polar applications, Landsat Arctic and Landsat Antarctic, as I’m sure you are going to want to explore and share the information you find. Esri’s Landsat Polar Applications Figure 3: Spectral profile view in Antarctic App Figure 4: Time tool with cloud filter in Arctic App Above, you can see screenshots of the Landsat Arctic and Antarctic applications, and some of the analysis tools built into the application. These applications support both visualization and analysis of the Arctic and Antarctic regions using polar stereographic projections required for working at these latitudes. Using them, you can easily access the latest Landsat polar scenes without the need to store, compile, and process the source data onto your local machine. You have full access to the temporal multispectral, panchromatic, and pan-sharpened Landsat scenes. In addition, you’ll notice the variety of easy to use analysis tools we’ve included in the left hand side of the application. These make it very easy to explore the imagery using custom band combinations, time profiles, and spectral profiles. The Spectral profile functionality plots the spectrum of all bands for a desired selected pixel and The Time profile provides a scalable timeline with the functionality to filter out clouds, simultaneously. These applications also include new Facebook and Twitter links. Try them out. When you share the image you are looking at, the shared link will bring a user back to the same location and state of the image analysis that you were at. It’s a great capability for sharing the information and imagery that you find interesting with others. Landsat Polar Services The Landsat polar services are available for use within the ArcGIS Online platform and are also part of the Living Atlas. These Landsat services and apps are open for public access. They can be directly used in ArcGIS Pro, ArcGIS for Desktop, ArcGIS Online web and mobile applications, as well as a wide range of applications that utilize the GeoREST Image Services API. The services are sourced from the scenes that remain in their original UTM projections, but have been published as a services with a default polar projection. All reprojection and mosaicking is being performed on the fly. When viewing them in ArcGIS Online it is optimum to use the Arctic Polar Ocean Basemap / Antarctic Imagery Basemap. Other polar projections may be used within their useful limits. These services can be used to support the work glaciologists and other scientists want to do in the polar regions including: reducing uncertainties of ice sheet mass balance estimates, providing a streamlined way to investigate associated sea level rise, refinement of ice sheet models, measurement of ice surface displacement/motion, ice-sheet topography, tidal effects over floating ice, ice sheet surface albedo, estimate of surface melt rates, ice velocity, etc. Accessing the various Polar services Figure 1: Arctic Service Figure 2: Antarctic service (Full view with NDSI Colorized: Blue regions represent snow, water. Yellow-green regions are cloudy, rocky areas.) The Arctic and Antarctic image services are separate and each is split into multispectral, panchromatic and pansharpened imagery. Currently the services contain all scenes collected since January 2015. In the Arctic, the GLS scenes that cover the Epochs of 2010, 2005, 2000, 1990, 1975 have also been added. The image services are updated daily to add new scenes as soon as they become available. Due to the fact that the Landsat satellite passes over the poles multiple times a day there is extensive temporal coverage. In the summer time when there is light and little cloud there is often a scene every day. Naturally in the winter months there is very little coverage. Below is a visual representation of each of the 6 different Landsat Polar Services available, along with hyperlinks directing to them. Landsat Arctic Views Landsat Arctic Pansharpened Landsat Arctic Panchromatic Landsat Antarctic Views Landsat Antarctic Pansharpened Landsat Antarctic Panchromatic Similar to the Landsat World services, the polar services have various raster functions to render different band combinations and indices like Natural Color with DRA, Geology with DRA, Color Infrared with DRA, Normalized Difference Moisture Index Colorized, and Panchromatic with DRA Sharpened. Two new raster functions Normalized Difference Snow index Colorized and Normalized Difference Snow Index Raw have also been introduced. Similar functions are available for the Antarctic service, as well. For more information, see the Arctic Maps , Antarctic Maps or Landsat Community groups on ArcGIS Online. You can also access the Landsat World Web App from Unlock Earth’s Secrets. Data Source The imagery in these services is sourced from the U.S. Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA). The data for these services reside on the Landsat Public Datasets hosted by Amazon on S3 storage.

Have you been eagerly waiting to use the new Sentinel 2 imagery from the European Space Agency in ArcGIS? The wait is over! Esri has enhanced ArcGIS to simplify the use of free, global Sentinel 2 imagery. Now the full 13 band multispectral and temporal information from Sentinel 2 imagery can be quickly accessed for visualization, interpretation and analysis. Sentinel 2 imagery is of value in a range of applications including forestry, agriculture, land resource management and environmental monitoring. This is exciting news since the Sentinel 2 data compliments Landsat data accessible through ArcGIS Online. You can now easily add Sentinel 2 scenes into ArcMap 10.4 and ArcGIS Pro 1.3 and immediately gain access to the wide range of bands combinations and indices combing the 10m, 20m and 60m spectral bands. Using a hot fix that same access can be applied in ArcMap 10.3.1. The resulting image can be viewed and analyzed using the advanced image processing and analysis tools available in ArcGIS. These include both pixel and segment based, supervised and unsupervised classifiers and can be expanded using python raster functions accessing NumPy and SciPy. Esri has also released a workflow that enables a large collection of Sentinel 2 scenes to be quickly served as dynamic image services. These enable the full information content of Sentinel 2 to be accessible to a wide range of desktop, web and mobile applications, with all processing being applied on the fly by ArcGIS Server. ArcGIS is ready to easily manage, analyze and disseminate the imagery and applications across institutions, organizations and new startup businesses, that are focused on land monitoring, maritime, climate and security. Here are the links you need!!! Workflow to create Sentinel 2 Mosaic Dataset Patch for ArcGIS 10.3.1 See this short video for an example of using an automated script to build and configure a mosaic dataset of your Sentinel 2 imagery.

The imagery team just posted a blog on the LERC technology we released today for making it fast, accurate and easy to share imagery and raster data over the web. The new approach to data compression enables you to set a tolerance for how much the compressed values can change from the original values. We call the algorithm that does this LERC (Limited Error Raster Compression). Using LERC, you can set a tolerance of 10 cm when you compress the data, and the result is a dataset that is compressed as much as possible while remaining true to that 10cm tolerance that you set. You can also set the tolerance to 0 which makes the compression lossless. In most cases LERC provides better lossless compression than traditional lossless compression methods such as LZW and deflate. Check out this blog post which gives you all the details, Storing large volumes of data in the cloud for more information. You can access LERC from our GIthub repository. Adding the link to the Press Release which has some additional information
