  1. Greetings Friend, We are here to share knowledge. Fraternal hugs from Brazil
  2. For you to perform the mapping with drone is necessary to perform autonomous flight. Start with small areas. Where you can see the drone. Good flights

    Thanks for sharing!!!!
  4. The answer for you, DJI user, is the DroneDeploy APP 😀 https://www.dronedeploy.com/
  5. Will the community really win anything ???
  6. Hawth's Analysis Tools Hawth's Analysis Tools is an extension for ESRI's ArcGIS (specifically ArcMap). It is designed to perform spatial analysis and functions that cannot be conveniently accomplished with out-of-the-box ArcGIS. Most of these analysis tools have been written within the context of the ecological applications I am involved in (movement analysis, resource selection, predator prey interactions and trophic cascades). However, they have been created in such a way as to be as broadly applicable as possible such that I hope people from many disciplines will find use in this set of tools. There are three types of tools in this kit. First, there are simple tools that automate mundane tasks (e.g. deleting many fields at once from a table). These will likely be useful to anyone. Second, there are tools that are designed to be part of an analysis workflow. For instance, random point (or stratified random point) generation, minimum convex polygon delineation, summarizing raster layers in various ways, etc. These too are likely to be useful to many people. Finally, there are tools that target specific, ecology related analyses (for instance, various movement model applications). These will likely only be of interest to ecologists. Specific detail of the tools can be found on the Tools page. Hawth's Tools is FREE. You are free to distribute it and install it anywhere you choose. As there are continual updates and additions to the tools, it is recommended that you check this website from time to time for more recent versions. I am always happy to hear constructive suggestions and comments about these tools. http://www.spatialecology.com/htools/overview.php Hawths Tools no ArcGis 10 e 10.1
  7. Vixe! Irmão... Eu havia entendido 500 pontos... Agora 500.000 (quinhentos mil!!! seis dígitos!!!) Amigo isso é humanamente impraticável... é trabalho para uma equipe e muito$ recur$o$....
  8. Saudações Fernando, pelo que eu entendi você quer que o arcmap encontre sozinho suas cisternas na imagem... é isso? Bom se for, eu desconheço esta função no Arcmap, porque ele é destinado a geoprocessamento. Talvez você consiga pelos programas mais robustos de sensoriamento remoto tipo Envi, ERDAS ou Ecognition .... porém também vai depender da qualidade da imagem que você está trabalhando e se todas as cisternas terão a mesma resposta espectral. De acordo com o que eu entendi na sua pergunta inicial você obteve os pontos das cisternas usando um aparelho básico de navegação por satélite, e os erros podem ultrapassar 30 metros... não acredite na mensagem do visor de erro de 2 a 5 metros... Outra coisa é qual imagem você está usando, procure ver se os Datum (Data) coincidem. No Arcmap você vai ter que acertar no braço mesmo. Sucesso...
  9. Fernando você fala Português?
  10. Greetings JR.... The spatial concept is very broad and will depend on its object of study. You can please try to improve your question. GIS is an established concept. "GIS" redirects here. For other uses, see GIS (disambiguation). A geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data. The acronym GIS is sometimes used for geographic information science (GIScience) to refer to the academic discipline that studies geographic information systems[1] and is a large domain within the broader academic discipline of geoinformatics.[2] What goes beyond a GIS is a spatial data infrastructure, a concept that has no such restrictive boundaries. In general, the term describes any information system that integrates, stores, edits, analyzes, shares, and displays geographic information. GIS applications are tools that allow users to create interactive queries (user-created searches), analyze spatial information, edit data in maps, and present the results of all these operations.[3][4] Geographic information science is the science underlying geographic concepts, applications, and systems.[5] GIS can refer to a number of different technologies, processes, and methods. It is attached to many operations and has many applications related to engineering, planning, management, transport/logistics, insurance, telecommunications, and business.[4] For that reason, GIS and location intelligence applications can be the foundation for many location-enabled services that rely on analysis and visualization. GIS can relate unrelated information by using location as the key index variable. Locations or extents in the Earth space–time may be recorded as dates/times of occurrence, and x, y, and z coordinates representing, longitude, latitude, and elevation, respectively. All Earth-based spatial–temporal location and extent references should be relatable to one another and ultimately to a "real" physical location or extent. This key characteristic of GIS has begun to open new avenues of scientific inquiry. https://en.wikipedia.org/wiki/Geographic_information_system
