Olá amigo assisto os seus vídeos, que por sinal são bastantes explicativos.Eu tentei me escrever no site earthexplorer.usgs.gov fiz todos os passos que foi me pedindo,quando eu digitei o número do telefone e cep , apareceu uma menssagem dizendo que nos Estados Unidos não se escreve daquele jeito, só que estou no Brasil.Como eu preencheria esta parte ?.Desde já agradeço.meu email é: [email protected]

Jorge, esse DEM SRTM chega a ser melhor que o TOPODATA 30m? que é derivado do SRTM de 90m

+ToMaZ NeTo Obrigado, Tomaz. O TOPODATA é o SRTM de 90 metros que recebeu a aplicação de diversos filtros para melhorá-lo. Em seguida, o pixel de 90 metros foi reamostrado para 30 metros. É o mesmo dado da NASA com alguns aperfeiçoamentos.

+Processamento Digital O topodata ainda é melhor que o SRTM. Jorge os vídeos são excelentes. Muito bom o seu trabalho. Certeza que muitas pessoas se beneficiam com esse trabalho...

Boa pergunta, Silas. Que tal gerar as curvas de nível e verificar os resultados? Abraços.

Estimado, le consulto por el tamaño de celda. Estoy trabajando en una zona montañosa y hay vacíos de más de 100 pixeles de ancho y alto, por lo cual no se si es conveniente tomar una celda intermedia (e.g. 20 o 25) e ir rellenando de a poco, o tomar una de 100 por ejemplo. Gracias!!

+SVTeko tiene que realizar la estadisticas de su zona de estudio. Puede utilizar otra imagen de respaldo (puede ser un Aster Gdem) para subsanar esos errores. Existen otras formas de rellenar, pero se necesita un buen manejo de estadisticas y se emplean distintas formulas.

I often find this occurs too. I have performed this function many times and believe it is part of the output of the program and the tool used. I have discussed this with colleagues and they agree. Often it is a product of the dataset that you use. We use it as predicted 'zones' . If you have access to other remote sensing data, ie Landsat or Modis then you should be able to extract water features from those directly. Does this help? PM me for email if you like

Hello on a DEM data pixel values has to do with elevation or it is just pixels value of the raster image? Im telling this because i created a DEM from vector data (contours) and in a small area of the contours data the contours line of 20m elevation is much far away from 0m elev contour line and in this area there are some pixels with negative values ( -2, -3 etc).. how can i get rid of negative values?

Hello sir .... I m facing some problems while extracting drainage from SRTM DEM... I do fill > Flow DIrection > and Flow accumulation.. and Using raster calculator... I found some of the streams appears as straight lines.... Can u please explain... why it happens and ... how to deal with it to get the natural flow of streams.. Please give me your E-mail ID..
https://gp5.googleusercontent.com/-KkqeZOHl6e0/AAAAAAAAAAI/AAAAAAAAAAA/ttTJJo4eljs/s48-c-k-no/photo.jpg?sz=64
this is a problem of your interpolation method! do you use spline interpolation or some more advanced shite like variograms? I wont try to remove them but would increase my databasis! have you just used contour lines for your DEM or soft break lines as well like streams and ridges? contact me via my channel here on youtube. best regards, riccardo

Algunas personas como Riccardo seguramente se pasaron varias horas investigando, o invirtieron en un taller de trabajo. Y además de hacer un video-tutorial algunos queremos el tema en un manual escrito. Esta bien Riccardo, pero que te paguen por ello. Tu trabajo te costo. Gracias por el Demo.

Hi sir, i am a phd student and want to map a canopy height of mangrove from srtm dem.i read alot of article but couldnt understand what is the process?is there any demonstration available about srtm canopy height mapping in arcmap? plz help me ?
https://gp5.googleusercontent.com/-KkqeZOHl6e0/AAAAAAAAAAI/AAAAAAAAAAA/ttTJJo4eljs/s48-c-k-no/photo.jpg?sz=64
i agree! but i would say the most important thing is the data (SRTM in this case) better data quality means better results. and srtm has height failures of about 16m which is a lot in flat area! you need to check with landsat data always!!!

good job. i mind if you have some tutorial about solar analysis in arcgis i was trying to determinate places to approach solar system but i can not get a good result. besides try in grass (r.sun) but do not work very well. thanks

Hello Riccardo, First, thank you for this and other videos, very well done. Can you provide any guidance for conducting these tasks against sonar data taken of rivers? Is the process and everything the same?

Fiz exatamente isso e nada, Beto. Coloquei na pasta usuarios do disco C:. Mas deu o mesmo erro. Eu uso um notebook com 3GB de RAM. 500 GB de HD e o Civil 3D está instalado no HD externo de 500GB que uso conectado ao note. Alguma outra sugestão?

+Beto Camelini Estou usando a mesma versão (no Windows 7) do amigo de cima e dá o mesmo erro. Já coloquei no desktop os arquivos e nada. Unable to read file. O que eu faço?
https://lh4.googleusercontent.com/-ZZXCQFdaomM/AAAAAAAAAAI/AAAAAAAAB_0/YGzV9vIsD7o/photo.jpg?sz=64
Talvez o arquivo esteja num local em que o Civil não consiga acessar. Tente colocá-lo em outra pasta.
