Perhaps the google statement should answer your question enough? Google makes no claims as to the accuracy of the coordinates in Google Earth. These are provided for entertainment only and should not be used for any navigational or other purpose requiring any accuracy whatsoever. Our imagery varies from sub-meter resolution in major cities to 15 meter resolution for most of the earth’s surface, with a global base resolution of 1KM. Since our database is constantly being updated, we cannot state a specific resolution for any geographic region. Google acquires imagery from many different sources with many different file formats, projections and spectral characteristics. All imagery sources are fused into a single global database with a proprietary format that has been developed for the specific purpose of streaming to our client software. the answer to your question, 'how accurate' really depends on where and what the source was.  could range from 2meters to many meters...  the decision is really then, how accurate do you NEED it to be.  I see legal boundaries cut through buildings on imagery for a reason... its not accurate enough. ...

if it's useful, this is how it is done with WABde and the result is more of what is expected from the OP. that no popup container shows up at all if there is no information when the action click occurs. File:  Server\apps\##\jimu.js\utils.js 'dojo/aspect' ... add aspect to the function() ... add the following lines (location in code in image) // hide the info window popup by default html.setStyle(map.infoWindow.domNode, "visibility", "hidden"); aspect.before(map.infoWindow, "setContent", function(method, args){           // show the info window if there are features, otherwise hide it           html.setStyle(map.infoWindow.domNode, "visibility", map.infoWindow.features ? "visible": "hidden"); }); ... View more

It is recommended to leave the configuration of a NAS appliance to a 'network' / IS / IT specialist. Not for a GIS 'anyone' to tinker with unless it is the GIS groups dedicated appliance and must be managed by them for whatever reason.  NAS typically is shared with more than just the GIS group and is more of an organization IS backbone appliance. Its great to 'know about it' but not recommended you act on it.   Scale-Out NAS for Unstructured & Big Data | Dell EMC Belgium  ... View more

Hi Randall, In my case, I had, and it was brutal. Was multiple weeks of conference calls and deep diving and I was in a position  with no luxury of time due to high business demands and limited resourcing.  EMC (the vendor for Isilon), eventually figured out how to get the NAS running without AGS issues, however, I had created a clustered environment mirroring the setup but used EMCs vMAX disks (SAN) and the performance was 10 fold different.  EMC failed to determine why the performance 'sucked' with the NAS in its configuration.  I had to pull the plug when we had reached week four and several 'specialists' from the vendor and the possible weeks/months more internal process for Isilon changes (because it was used as a 'network' drive for many business groups)  I went out of my way to resubmit an architectural change and introducing a single point of failure with the SAN setup.  Far better than tinkering with that NAS let me tell you. ...

For reference, the best approach I have found to work without ever having an issue is to do the following: Add a clientCache control (in the web.config) and set the controlMaxAge to your desired time. e.g.  <!--expire after 1 day--> <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="1.00:00:00"/> ...

More than likely, whomever administers or configured your NAS has OpsLocks enabled.  Disable OpsLock and your issues will likely be gone.   I prefer using SAN for the superior performance of a NAS. I had posed similar earlier in the thread.  Isilon is a NAS appliance. ... View more

You can start here: Licensing & Attribution | ArcGIS API for JavaScript 4.8  You can dive deeper here: Full Master Agreements - Products and Services Terms of Use and Changes | Esri Legal  There are additional links and legal jargin as well (such as the details on the Tile transaction limits and yearly limits to go offline.

Pro 2.0.x  has a bug that fails opening .tpk files.  Funny thing is that the latest version Pro 2.1.3 has fixed this, but then esri broke the ability to Create Map Tile Package which HAD worked in 2.0.x.  Many ESRI products read .tpk files, including desktop products, Enterprise products and developer products. ...

You will have to change to using the Google API for your web App (UI) if it is a must. It is against the Legal agreements outlined with Google to use Google Street view without using the Google API.

Hi Mervyn, This is the response I was expecting.   Just making sure it inst something else, as in settings in D2M or.. So the cause is due to different flight days or just the fact that each flight taken has the open window of the accuracy (e.g. 5m HDOP) error to create the shift - GPS image tile reference.  There is some math involved knowing sampling would increase accuracy (reduce the HDOP) to some log factor - maybe 2.1 meter. and yes, all image tiles are tied to the GPS as this is the reference. Do you feel this statement is valid in understanding what is causing this shift? To validate one could, strap on a better gps device with RTX OmniStar satellite correction and run different flights and if the above hypothesis is correct, would drastically reduce or even eliminate the shifts seen above. Unfortunately, do not have the funds to do such an experiment. I was not aware that Pro allows you to correct / rubbersheet to another image.  (sounds like a poor mans fix but the option is there) - like you said, you need a valid reference image.  And I am not sure how well that would work for tying a shift as seen in the attachment when that occurs at one end of the flight... what about the tail end that has no image to reference to? (it stays out of whack?) With that being said, what can be done with avoiding or correcting after the images have been collected? 1.   Create ground control points (surveyed) and rubber sheet the image? 2.   Create ground control points (surveyed) and use in the D2M software - manage GCPs. 3.   Increase accuracy of GPS Device (better device) 4.   For elevation correction (one can reference a known accurate DEM) to correct altitude - doesn't help with shift though. 5.  ? ...
