Hello, guys, Any advice on ArcGIS/ ArcGIS Pro desktop installation in Linux Deepin (desktop and server)? +++++ Just check the doc on a Mac at https://pro.arcgis.com/en/pro-app/get-started/run-pro-on-a-mac.htm, which looks that it is going to be very promising via VMware Fusion, parallels. What about it in Linux (Deepin) via virtualbox, parallels, or VMware ? ... View more

Hello imagery associates,   When loading the bundle Pleiades-1 RAW data (i.e., bundle 0.5m Panchromatic and 2m Multispectral under folders) into Mosaic Dataset, do you witness the following?   The standard Pleiades-1 template (attached) works fine with Mosaic Dataset in ArcGIS 10.4 or 10.4.1.:           ... Completed crawling 470 data source items. Added 470 mosaic dataset items. However, this Pleiades-1 template is not functional at all with ArcGIS 10.5/ 10.6.1 and ArcGIS Pro, even though it is applied onto the same bundle Pleiades-1 data folders with all same options: ArcGIS 10.5/ 10.6.1: Start Time: Sun Sep 16 13:28:32 2018 2018-09-16T13:28:32.066: Loading raster datasets 2018-09-16T13:29:12.046: Completed crawling 470 data source items.

It should not be a bug, but no other root causes to dig.  I would like to confirm with you, if any similar or reproducible observations. ... View more

Hello, desktop teams, As well-known to ArcGIS /ArcGIS Pro users, most types of databases require users to install and configure a database client on the machine that will connect to the database. For example, they have to install Oracle instant client (32-bit, 64-bit) with the Path environment variable properly configured, after desktop ArcGIS /pro installed.   In practice, it is very troublesome, especially, in an enterprise (the tight security). In fact, we witness that this type of database-oriented installation/ configuration steps are very hassle to non-IT professionals like economists, engineers and geoscientists, even very often to many IT support guys.   Just wondering if ESRI can build one single desktop ArcGIS installer (32-bit) or ArcGIS Pro installer (64-bit) for enterprise users, which include major supported database clients like Oracle instant client (32-bit or 64-bit) and path environment to be configured properly.   As an example, ArcGIS Pro 1.4 or later already implement similar for Python 3 (Conda), which certainly demonstrates much better productivity and efficiency to help enterprise users. please advise ...

Hey, guys Many of our LAS data (which were not processed/ classified by the data vendors) urgently need edit and clean up, in particular, detection and removal of massive ‘outlines’.  After well done in this way, we expect that the results of LAS data can well represent DSM (digital surface model). Of course, those DSM will be used to do further processing and analysis. The question is: In ArcGIS, any effective GP tools can be used to assist us to meet this goal? Ideally, a GP tool that utilizes RANSAC algorithm (random sample consensus) is available. If not, any alternatives? Please advice ... View more

Hello, data analysis and business intelligent team, As well known,  with the assistance of Exploratory Spatial Data Analysis (ESDA) tools in ArcGIS, we can get deep insight about our data, so that those analysis results can help us to choose the best interpolation algorithm and also the right analysis methods. Similarly, the Exploratory Regression (ER) analysis tool is also widely used for data analysis practitioners to easily find a properly specified OLS model (Ordinary Least Squares). Sometimes, it certainly works good, especially, when no extreme outliers in the datasets. However, many factors and technical considerations drive us to consider the combination of both ESDA and ER analysis methods together in practice, because we believe that will significantly improve the reliability of the analysis model and prediction accuracy, in particular, for detection of outliers (spatially over time) ... So, as data analysts, please share any relevant thoughts about this? For example, advantages and benefits, some cautions ... when combing both together in your applications. Regards, ... View more

Hello, fellows, With Conda and Python Package Manager, ArcGIS Pro 1.4 offers a great way to install and update external open-source Python packages. Plus with the support of R (Microsoft R Server) via R-ArcGIS binding, ArcGIS Pro 1.3/ 1.4 has gradually become an innovation platform in development environment, especially for raster and data analytics ...  However, it is still challenging for us to install and update behind the firewall (in the enterprise environment), particularly Python packages in ArcGIS Pro. For example, first to determine and download all dependencies of the Python package (saying, TensorFlow, openCV, etc.), including dependencies of those dependencies (dependency tree), into a local repository (copy and transfer to this repository), and then automatically to install from the local repository behind the firewall.   So, does ESRI have plan to improve the Python Package Manager sooner? Or, is there any 'effective & reliable' way to automatically create a local Python package dependencies and dependencies of those dependencies first, and then automatically install those into ArcGIS Pro from the local repository in the enterprise (via conda, pip or any other)? (Relatively, much easier for us to do with R packages and dependencies for ArcGIS Pro ..., even not effective) Regards, Larry @ ARAMCO ... View more
