    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

    TESS, the satellite launched by NASA last month that will search thousands of stars for Earth-like exoplanets, has just sent back its first test image. It’s just a quick one, not “science-quality,” but it does give you an idea of the scale of the mission: the area TESS will eventually document is 400 times the area covered by this shot. What you see above is the star field around the constellation Centaurus; this 2-second exposure captured more than 200,000 stars. That’s just in one image from one of the four cameras on board; the Transiting Exoplanet Survey Satellite will employ all four during its mission, watching individual regions of space for 27 days straight over the course of two orbits. Repeated high-resolution imagery of these star fields will let the team on the ground watch for any that dim briefly, indicating that a planet may be passing in between the star and our solar system. This will let it watch far, far more stars than the otherwise similar Kepler mission, which even by looking at only dim stars with a relatively narrow field of view, found evidence of thousands of exoplanets for scientists to pore over. TESS just yesterday received a gravity assist from the moon, putting it near its final orbit. A last engine burn on May 30 will complete that maneuver and the satellite will enter into the highly eccentric, as yet untried orbit designed by its creators. Once that orbit is attained and all systems are go, new imagery will come in about every two weeks when TESS is at its closest point to Earth. “First light,” or the first actual fully calibrated, usable image from the satellite, is expected some time in June. https://techcrunch.com/2018/05/18/nasas-newest-planet-hunting-satellite-takes-a-stellar-first-test-image/

    @ASalas Also adding to pasfans01 answer 2., keep in mind that if you want to use NDVI for data assimilation puproses (e.g. compute vegetation biophysical parameters etc.) you will need the Surface Reflectance (Level 2A) data to produce the NDVI map, since 2A are more close to the true radiance values. For more information, you could read the sentinel 2 users guide that ESA offers. If you use the 2A data, in your case it would be of great help to first check the quality assesment data in order to see and assess the impact of cloud coverage in you scene. Regards

    I think you have better luck using a Photogametry softwares like 3DZephyr, Pix4d , or Photoscan than global mapper.

    I think it is possible using WV3 What kind of analysis you going to perform ? single time or multitemporal. Multitemporal analysis going to needs more imagery rather than single imagery. If you only have single imagery covering certain region, what you must first do is develop or looking for spectral signature of bamboo tree, after that you can perform smooth classification like linear spectral unmixing, or hard classification like maximum likelihood to extract the bamboo forest based on those spectral signature. machine learning segmentation can also be used, some software has implemented machine learning classification which is very advanced and has been used widely. If you have multitemporal imagery, it will be better, because now you are enabled to monitor vegetation dynamics over the observation period. You know at certain season, vegetation will drop it leaf and regrowth it at the spring or summer. And every vegetation type behave differently to weather and climate, that information can be used to separate one type of vegetation to another one, include bamboo. good luck

    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. "

    a new global WebMap prototype “OSMLanduse.org” has been launched by GIScience Research Group Heidelberg. The map provides worldwide Landuse/Landcover informationon the basis of OpenStreetMap (OSM) data. This is based on our earlier work on testing the suitability of OpenStreetMap for deriving landuse and landcover information (LULC). LULC data is highly relevant for many research questions and practical planning activites. Up to now there exist well known data sets generated from remote sensing imagery such as CORINE, Urban Atlas or GlobeLand30, which are available for different areas, time slots, and offer different LULC classifications. Yet it is an interesting question if and to what degree OpenStreetMap can complement, add to, or refine these sources. Up to now this is certainly very different in different world regions and the new map helps to explore and better understand this kind of data in OSM and how it is evolving in different areas. Therefore the aim is to evaluate the overall possibility and suitability of OpenStreetMap (OSM) data for these specific purposes, identify ways for improvement and to provide all this information globally to the interested communities in an automated way. In order to do so, the data from OpenStreetMap, stored in Key-Value pairs, was initially categorized similar to the classification level 2 of the CORINE Landcover classes. This category mapping and further pre-processing of OSM data will be further refined in ongoing work. A first basic WebMapping application has been set up with the use of free and open-source software, including PostgreSQL/PostGIS, Geoserver and MapProxy. At the moment the website provides basic WebGIS elements, such as legend, search function and feature info. Higher zoomlevels (>7) are updated on a minutely basis. In the near future we want to implement other useful features and explore ways to measure the quality of the data. Right now GIScience HD isworking on realizing a function, which provides statistical information about the landuse/landcover in a certain area (bbox), defined by the user. In particular also the mapping between common land use classifications such as CORINE, Urban Atlas etc. and the OpenStreetMap categorization of objects is refined and the preprocessing for different scales improved. site : http://osmlanduse.org/

    this is the tricky part if you have an area with dense forest, then I only think 2 ways : 1. You can extent your area to the place that contain open small area and you can place the GCP there 2. You can use specific natural object as GCPs

    I have 2 questions for Lurker: 1) do you need a special permission, a legal document to fly a drone in your country ? For example in USA, drone operators need to register (and to pay a fee) to Federal Aeronautical Agency, and similar situation is in some west European countryes ? How is in Indonesia ? 2) do you use Ground Control Points (GCP's) marked on the the land surface with the GPS when you fly your drone, to produce accurate orthophoto mosaics ? Thank you. Arhanghelul

    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,

    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.
