    You can download for free ArcGIS Desktop (ArcMap) 10.6 legally for one year (extendable to two), non-commercial, with all extensions through a student license that grants enrollment in a Coursera course. Below are the steps to download and install ArcGIS Desktop for free (please follow the instructions exactly). 1.- Register in Coursera and confirm the registration email. 2.- Enroll in the Fundamentals of GIS course (in the blue button of the left panel). 3.- In the new “7-day Free Trial” window, click only on the lower part of the window on Audit the course. 4.- Request an ArcGIS Authorization Code and accept the conditions. 5.- Check your email (spam folder) sent by UC Dacis Coursera Team with subject ArcGIS for Desktop Student Trial License, and look for the License Key code. 6.- If you have an Esri account omit this step, otherwise create a new Esri account, accept the conditions and activate your account with the conformation link that comes to your email. 7.- Activate your authorization code at www.esri.com/educationedition by selecting I have an Esri Account, here enter the License Key you received in your email (step 5). 8.- In the new window select ArcGIS Pro 2.1 / ArcGIS 10.6 (or the version you require), then download ArcGIS Desktop (ArcMap), it is recommended to use the English version. Optionally, you can download and then install ArcGIS Data Interoperability for Desktop (ArcMap). 9.- Install ArcGIS Desktop, in the installation wizard set the installation type to Complete, and proceed with the following button until the installation is complete. https://acolita.com/wp-content/uploads/2018/06/Instalar-ArcGIS-Desktop-10.6.png 10.- When the installation is finished, it shows the ArcGIS Administrator window (if it was closed you can open it from the Windows start menu).11.- In 1. Select a product, on the right side select Advanced (ArcInfo) Single Use, in 2. Launch the Authorization Wizards for Single Use products select Authorize Now. Credit to GEO GEEK WEBSITE https://acolita.com/wp-content/uploads/2018/06/ArcGIS-Administrator.png 12.- In Authorization Options, select the first option “I have installed my software and need to authorize it“.https://acolita.com/wp-content/uploads/2018/06/Opciones-de-autorizar-ArcGIS-Desktop.png 13.- In the next Authorization Method window, select the first option “Authorize with Esri now using the Internet“. 14.- In the following windows Authorization Information fills in the requested fields with the personal data of your Esri account, then the organization data select Education, Industry Higher Education, in yourself Student. https://acolita.com/wp-content/uploads/2018/06/Autorizar-Informacion-ArcGIS-Desktop.png 15.- In the next window enter the License Key code you received in the email (step 5, similar to EVA123456789).16.- Now in the Authorize Software Extensions window select the first option “I do not want to authorize any extensions at this time“. 17.- Finally in the Evaluate Software Extensions window, do not make any changes, leave it by default and click next. 18.- Open ArcMap and enjoy for a year, after that time you remember “GeoGeek.xyz” and repeat the process to activate another year (unless Coursera does not want to give us more licenses), the student version is full, but only valid for two years for each Esri account. Don’t forget to activate the extensions from the Customize menu, if you want to learn ArcGIS you can download the book Fundamentals of GIS. This “trick” comes thanks to Geo Sem Fronteiras, who so far (18/06/2018) works without any problem. If you think it’s been useful, don’t forget to share with your entire geopeople.

    Styler is a new ArcGIS configurable application that can be used to easily create, style and share modern 2D and 3D map apps. Using simple styler parameters you can customize everything from the title, menus and text, to the overall color, theme and layout. The app is hosted on ArcGIS Online and GitHub so you can 1) style maps on-the-fly just by adding URL parameters or 2) if you have an existing web map or web scene, you can style (more advanced) apps step-by-step by configuring them with the new Styler template. Once styled, share your app at any time just by sharing the URL - no programming required. Styler is built with the new ArcGIS API for JavaScript v4, Calcite Maps and Bootstrap. The application is fully responsive and supports many features of the new JavaScript v4 API such as loading 2D web maps and 3D web scenes, displaying image and vector tile basemaps, showing legend and layers, positioning widgets on the view, and searching and finding places. The app can be accessed in ArcGIS Online and ArcGIS Enterprise or downloaded and hosted locally. How to style and share a map Open the default 2D map or 3D scene and zoom to or search for a place. e.g. "New York City" https://esri.github.io/calcite-maps-styler-template/index.html?webmap=default https://esri.github.io/calcite-maps-styler-template/index.html?webscene=default Click the Main Menu > Share, add URL style parameters and hit Enter to style your map. e.g. https://esri.github.io/calcite-maps-styler-template/index.html?webmap=default &title=New York City at Night &bgcolor=dark-blue &basemap=streets-night-vector &lat=40.72461 &lon=-73.99893 &zoom=12 Now copy and paste the URL to share your map with others. https://github.com/Esri/calcite-maps-styler-template

    1. For the shadow, it will make the NDVI values close to zero, whatever the landcover covered by it 2. for level 1C data, the digital number/reflectance is processed to top of atmosphere value, which means atmospheric effect is not yet corrected, and for level 2A, the digital number/reflectance has been corrected to surface/bottom of atmosphere reflectance (atmospheric effects has been corrected). Theoretically , the level 2A data will give more accurate NDVI values compared to level 1C,

    I know by experience when i was visiting a project site in Western africa , if you see a black dude with an AK-47 near an alluvial areas, then that is where the Diamonds are. i hope that helps.

    Hi Paolo, Remember from my text: "collect around 200 l of alluvial, concentrate by panning, then carefully observe the heavy minerals associations". I saw some papers telling about 100 kg (the minimal I think). We were more conservative and prudent in some projects. It is a large quantity; depending on on the pan size, at least 10- 20 pans to wash. Finally, depending on the area, you will obtain some hundreds of grams of heavy minerals; among them, a lot without significance, like magnetite. And then, in less quantities: pyrope and eclogitic garnet, chrome diopside, picroilmenite, chromite; and, to a lesser extent, olivine . The indicators. These are the indicators about a kimberlite body. The kimberlite is decomposing fast and will leave this mineral traces in the alluvial, but diluted with other minerals, depending on the distance. It is what you are searching. Personal (from some sustained field experience, and also a lot of study for Remote Sensing or GIS) I don't think that you can discriminate those minerals, in such small quantities, basis on remote sensing, in alluvials. To few, in order to have a significant spectral signature. See an article, about the kimberlites* As a good help, starting from the satellite data, you can do a geomorphological analysis. Discriminate well and precise the hydrographic network, then to locate some favorable areas (terraces, dejection cones), for heavy minerals concentration. Among them, beside the indicators, you can find, or not, diamonds (3.52 SG). It is what I done, in my projects. Not Angola, but nearby. Then, to start exploring, as I wrote before, on the ground. Or direct mining, with the risks of acquiring heavy equipment and be without enough reserves. I don't know if you have an exclusive license; if yes, can you send me the coordinates, in order to see what it is available (satellite) for that area ? If you are prospecting, and the area is confidentially, please send something like an nearby area, one-two hundreds kilometers distance. They are some new satellite data and I want to see the confidence, if you are agreed. Regards, Iulian * http://www.hgimaging.com/PDF/Kruse_IEEE2000_Kimberlites.pdf "Higher spatial resolution data (1.6m AVIRIS and 4m HyMap acquired in 1998 and 1999, respectively) are being used to map additional detail. Poor exposures, vegetation cover, and weathering, however, make identification of characteristic kimberlite minerals difficult except where exposed by mining. "

    1. recently after drone booming our government made a legal document to regulate drone , I think the main point or focus of the regulation is place that near airport or near military facility, or other official building, if you fly it on remote area or area far from plane route I think its okay to fly it without permission. This legal document regulate to send a permission before flying a drone. We dont have a drone operator registration yet. 2. of course, if your drone data isnt GSP'd , then your data useless for detail analysis, we use geodetic GPS to make a GCP. (Topcon GR-5) and we use a banner (1.5 m x 1.5 m) for land marking. this is the most exaustive part of drone project

    just adding some information, when you want to build a UAV you need to know what your purpose, whether you need a copter or fixed wing, both have advantages and disadvantages I give you example from our project copter, easy to navigate, easy to control, suitable for small area, relative detail since copter can fly in low altitude. travel only in short distance compare to fixed wing fixed wing, suitable for large area, can fly in tenth of kilometers, hard to control especially at landing, cannot fly in low altitude,

    You cannot compare two software bluntly. ERDAS Imagine has it's own user group in commercial resource management and exploration sector. ENVI also has it's loyal customers in universities and private research groups. The reason ERDAS is so popular in Asia and other places because they have a very good marketing department set in these places. The reason why ENVI can't get out of the wish list is most of the American and EU graduates can't give up using IDL for so many engineering and technical studies. IDL is awfully interesting for geeks, sometime as powerful as Matlab. ITT corp has their money flow steady by its global network of big scale industries, ie. aerospace, transportation, defense, energy and industrial markets. Now ITT is one of 100 top contractor in USA. Intergraph corp is more focused in engineering and geospatial solution since it's beginning (may be that's why they are good at selling their products). ERDAS Imagine, being an adopted son for so many parents over time (starting from the universities of America and Canada) ended up with Intergraph after touching many big names in its path. During its journey the software inherits codes and ideas from many experts, started its algorithms written in Fortran and later rewritten to C, sometimes Python. Being closely tied with a robust Fortran-derived interactive language, ENVI is a cross-platform image processing monster hugely popular among academicians, engineers, geospatial analysts, modelers and programmers. If you are a novice image analyst, ENVI is your thing. If you are a power user, application builder, environmental model maker/ tester, medical scientist, even a rocket scientist you will find ENVI sitting in you pc. But remember, great power comes with great responsibilities. If you are a white-collar GIS analyst, ERDAS Imagine is your thing. This software has it's charm in doing small things quickly and in a stereotyped way. In Imagine, things are easy once you learn the names of the buttons. Every function has only one wizard so learning curve is flatter. If you are a hobbyist, professional with little or no geospatial background, lousy professor then Imagine is your tool. Consider taking a peek to the other big names attached (ie. GeoMedia) to know how Intergraph deals the 'other-part' of geospatial industry. As you can see, every one has their own vice and virtues. Choose wisely.

    I am researcher and I never think about this. Of course the specialties can be different and I imagine the most of you work in spatial things but not only that, more specifically in physical geography, I am geographer but work with social aspects. but if We see the main aspect in this topic We see a big, big problem if We are thinking in that; any cracked program you use to do the research, even the word processor, spreadsheet, unpacker, the operating system, must have the same relevance over research. If that is the situation no more research for us, because in some or a lot of cases maybe We can pay for license, but no buy shoes, food, water, etc for a time. For me that is nonsense, because the idea in research is find new knowledge, ideas, procedures and that is the significant We need to see. But if you think that is important, if you have a license or not and that is a requirement in Published standards, definitely yo can´t do research. And in that case try to write, calculate, execute the program and run the simulator, where is a licensed software, to meet the requirements that "System" claims, not the science (if this even is valid to) if you discover something new with or without license that is a discover and no matter if this was with a paid license or not, that is my opinion.
