    • Does anybody know how to do the equivalent to ArcGIS function Feature to Polygon in an Open Souce free software? Like QGIS, although I haven't found how to do that in QGIS. The ArcGIS function is this one: http://desktop.arcgis.com/en/arcmap/10.3/tools/data-management-toolbox/feature-to-polygon.htm Thanks
    • Hi everyone, we're looking for testers for our new EOS Platform. It is a cloud-based platform you can use for geospatial analysis. There are 4 tools included, each has its own functions and they all are mutually integrated, which means you can quickly switch between various tasks and use same data across all the tools.   And here are some things you can do: - search, preview, download satellite images (Sentinel-1,2, Landsat 8,7,MODIS, NAIP, etc.) and calculate spectral indices on the fly /this is a tool called Landviewer/ - save the imagery you've found or upload your own from computer, store it in the cloud, share and distribute /this tool would be EOS Storage/ - apply image processing algorithms, you’ll find some basic ones like raster calculator, merge, pansharpening, and the more cool ones built for certain industries (flood detection, forest classification, ag land borders detection, object detection and more) /This is EOS Processing/ - visualize vector data and create maps /EOS Vision/
       
      The platform is in open BETA: https://eos.com/platform And there’s no limit on testers, so everyone is welcome to give it a try and post questions or suggestions to this thread! Anyone interested?
       
    • Which WEBGIS Software can be used with Google Cloud??
    • Maps needs fixing. Apple, it turns out, is aware of this, so it’s re-building the maps part of Maps. It’s doing this by using first-party data gathered by iPhones with a privacy-first methodology and its own fleet of cars packed with sensors and cameras. The new product will launch in San Francisco and the Bay Area with the next iOS 12 beta and will cover Northern California by fall. Every version of iOS will get the updated maps eventually, and they will be more responsive to changes in roadways and construction, more visually rich depending on the specific context they’re viewed in and feature more detailed ground cover, foliage, pools, pedestrian pathways and more. This is nothing less than a full re-set of Maps and it’s been four years in the making, which is when Apple began to develop its new data-gathering systems. Eventually, Apple will no longer rely on third-party data to provide the basis for its maps, which has been one of its major pitfalls from the beginning. “Since we introduced this six years ago — we won’t rehash all the issues we’ve had when we introduced it — we’ve done a huge investment in getting the map up to par,” says Apple SVP Eddy Cue,  who now owns Maps, in an interview last week. “When we launched, a lot of it was all about directions and getting to a certain place. Finding the place and getting directions to that place. We’ve done a huge investment of making millions of changes, adding millions of locations, updating the map and changing the map more frequently. All of those things over the past six years.” But, Cue says, Apple has room to improve on the quality of Maps, something that most users would agree on, even with recent advancements. “We wanted to take this to the next level,” says Cue. “We have been working on trying to create what we hope is going to be the best map app in the world, taking it to the next step. That is building all of our own map data from the ground up.” In addition to Cue, I spoke to Apple VP Patrice Gautier and more than a dozen Apple Maps team members at its mapping headquarters in California this week about its efforts to re-build Maps, and to do it in a way that aligned with Apple’s very public stance on user privacy. If, like me, you’re wondering whether Apple thought of building its own maps from scratch before it launched Maps, the answer is yes. At the time, there was a choice to be made about whether or not it wanted to be in the business of maps at all. Given that the future of mobile devices was becoming very clear, it knew that mapping would be at the core of nearly every aspect of its devices, from photos to directions to location services provided to apps. Decision made, Apple plowed ahead, building a product that relied on a patchwork of data from partners like TomTom, OpenStreetMap  and other geo data brokers. The result was underwhelming. Almost immediately after Apple launched Maps, it realized that it was going to need help and it signed on a bunch of additional data providers to fill the gaps in location, base map, point-of-interest and business data. It wasn’t enough. “We decided to do this just over four years ago. We said, ‘Where do we want to take Maps? What are the things that we want to do in Maps?’ We realized that, given what we wanted to do and where we wanted to take it, we needed to do this ourselves,” says Cue. Because Maps are so core to so many functions, success wasn’t tied to just one function. Maps needed to be great at transit, driving and walking — but also as a utility used by apps for location services and other functions. Cue says that Apple needed to own all of the data that goes into making a map, and to control it from a quality as well as a privacy perspective. Though the overall project started earlier, the first glimpse most folks had of Apple’s renewed efforts to build the best Maps product was the vans that started appearing on the roads in 2015 with “Apple Maps” signs on the side. Capped with sensors and cameras, these vans popped up in various cities and sparked rampant discussion and speculation. The new Apple Maps will be the first time the data collected by these vans is actually used to construct and inform its maps. This is their coming out party. Some people have commented that Apple’s rigs look more robust than the simple GPS + Camera arrangements on other mapping vehicles — going so far as to say they look more along the lines of something that could be used in autonomous vehicle training. https://techcrunch.com/2018/06/29/apple-is-rebuilding-maps-from-the-ground-up/  
    • Hello, I need to combine two overlapping raster layers. I would like the resulting map to get the values such that it takes the higher values from any of those two layers. For example:If one map has a value of 0.8 and other has 0.1 at same point then i would like the final map to get a value of 0.8 from the first map.    How could this be done in arcmap? Can someone help me with it?   Thanks a lot, Maaya
