In the vector buffer area, which category of the raster is the most

2018-10-17 Thread Eddison Araya 
Hello Kirk thank you very much, maybe my email was not clear, what I want
to calculate is the median (https://en.wikipedia.org/wiki/Median) and not
the average, I do not know if it is clear, but what I want to calculate
it's the median and not the average between the images.

Then how can I calculate an image 6 that represents the median?

Thank you

Hi, if I'm using QGIS, only that was a screenshot that was sent to me at
the beginning.

I can not send the image because the size is large, I attach the image
here: * https://ibb.co/b15WF9 <https://ibb.co/b15WF9>*

Hello, greetings, a question:

[image: image.png]

If I have that map:
*https://www.dropbox.com/s/6hvnrb37fvc00wl/ejemplo.zip?dl=0

E eu quero dizer:
 Se W_BRILLO is equal to 3, se W_PPT is equal to 1, se W_TEMP is equal to
2, have a value of  2

Se W_BRILLO   is equal to2, se W_PPT  is equal to2, se W_TEMP is
equal to   3, have a value of 2

Se W_BRILLO  is equal to1, se W_PPT  is equal to2, se W_TEMP  is
equal to3, have a value of 3

I put this:

CASE

WHEN "W_BRILLO" = '3', "W_PPT" ='1', "W_TEMP" = '2' THEN 2
WHEN "W_BRILLO" = '2', "W_PPT" ='2', "W_TEMP" = '3' THEN 2

Hello, I used ODK Collector connected with Google Drive to perform field
surveys.



As you can see, the X and Y coordinates are contained in the same column
when using the ODK Collector APP, connected to the Google Drive Sheet. How
can I take that to QGIS? I have tried to use the function Add Layer of
Delimited Text I can not do it since the coordinates are in the same column.

Thank you

Hola Manuel, una solución es la siguiente:

[image: Imágenes integradas 1]

1. Ir a Vector > Geoprocessing Tools > Buffer y generar los buffer normales
con el radio que usted necesita definir

2. Luego crear una capa con la extensión del tema de buffer: Vector > Research
Tools > Polygon from layer extent.

Saludos

[Qgis-user] -: Instalación avanzada de QGIS 2.12 LYON

2015-11-25 Thread Eddison Araya 
Estimados amigos (as), hice la instalación avanzada siguiendo los pasos de
aquí:
http://geoblog.alwaysdata.net/2015/instalacion-y-configuracion-de-herramientas-foss-e/
para
instalar la versión QGIS2.12 LYON.

Mi maquina es una de 64 bits con Windows 7 Profesional

Cuando intento correr el Monteverdi 2 dentro del menú Osgeo me pone el
error de que falta el archivo qwt5.dll, alguien sabe por favor de que se
trata? y el Monteverdi 2 no ingresa.

Muchas gracias

Hi, I have a problem with the installation of GEarthView. The complement is
broken, and the program said No module named sope.interface. I manually
download the complement but I don't know how install it?
Can you help me? Thank you!
