Conversion of Meters to Long and Lat

I am using INSAT 3D insolation data at L2C level for my research work and I am trying to visualize in MATLAB. In the data file it is clearly mentioned the unit of latitude and longitude is in 'meter' in X and Y variables in the data set. So, I am dividing with 111000 for the conversion from meter to degree but I found the output is wrong. If any one can please help me to understand the conversion. Also, I have attached the data file please have a look.

I have collected some coordinates using Trimple Juno ST GPS.

In GPS i sett the all option related with the Geographic coordinates.

Projection=UTM,Datum=WGS 84,Zone=40

While i am collecting this coordinate manually i had wrote each coordinates in paper.

It is meter format.

Example

Latitude : 2783080.04 meter North

Longitude : 322440.32 meter East

How i can this manually written Coordinates convert in to degree minute second format.

Can any one help me to do this please.

I want to know how extract of precipitation data for specific coordinates (longitude/latitude) from the netCDF file that I downloaded. Or how to convert the file from netCDF extension to CSV file. I'll be Thankful for any help.

I want to compare ERA Interim precipitation estimates with ground measurements so i do not know to convert the data from kg/m2/s to mm/day.

Thanks in advance

Hello,

I am working with Vegetation Indices, among them the EVI. I read the Huete et al., but I am not sure what the values of the EVI means. If I understand it correctly, A healthy forest should be in NDVI ~ 0,85 and in EVI ~ 0,7. A dry savannah in NDVI ~ 0,7 and in EVI 0,4. Is it correct? DO you have other sources for the interpretation?

I am looking for a code which I can use to convert a netCDF file for specific region such as Mozambique Channel. I am able to download, read a netCDF file for an oceanography variable in R. But I did not find specific code to convert a netCDF data file in CSV or txt file which I can easily use it in R for my interesting research. Can anyone help me to find or share a code wihch will enable me to convert a netCDF in CSV data file for time series such as 2000-2020 for the area delimited by Longitude (30ºE - 50ºE) Latitude (5ºS -40ºS) for a variable SST or pH?

hi

I have 11 netcdf files, each of 5 years durations for a particular search constraint.

1951-1955,

1956,1960,

1961-1965

and so on till 2005

now I want to combine all these files to make one single file starting from 1951 and ending at 2005

anyone can plz help me what nco command should I use?

Hello:

I wish to calculate Vertically Integrated Water Vapor Transport on a daily basis using ERA-Interim dataset and present a composite map for the same for a 10-day time span. Is this IVT values are directly available at ERA-Interim repository, how to present 10-day average for this. Please suggest how to do so.

( I want to create a Geological map with Gneiss as a base layer. but the same unit is present within the boundary of an upper layer of Charnockite. I need to draw each without overlap)
