If the degree coordinates should be in Helsinki (for which UTM zone 35 is correct), you should enter 24.9993393, 60.184716. Note that proj expects East - North order, with negative singns for Southern and western coodinates. Converted to EPSG:3067, the coordinates are 389042, 6673664.

The correct syntax is: cs2cs +proj=lcc +lat_1=41.03333333333333 +lat_2=40.66666666666666 +lat_0=40.16666666666666 +lon_0=-74 +x_0=300000 +y_0=0 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=us-ft +no_defs +to +init=epsg:4326 -f %%.8f<nad.txt >out.txt with 987043 206407 in the input file nad.txt to get this output: -73.98992216 40.73321572 ...

Use functions from the sp and rgdal packages. Assuming your shape file is named myshp library(sp) library(rgdal) proj4string(myshp) # Gives the CRS of the data myshp=spTransform(myshp,CRS("+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs")) # To convert it to WGS84 ggplot2 input has to be a DataFrame, to convert a SpatialDataFrame to a DataFrame named ...

use Heg tools. You can save to tif and reproject to geographic coordinates. Also you can use batch.

There is a MODIS Reprojection Tool available from the USGS here: https://lpdaac.usgs.gov/tools/modis_reprojection_tool You'll need to create an account to download it, but the registration seems painless.

With an unknown coordinate system you need to use trail an error... but in this case NAD 27 datums would probably fit the best. You can compare it with the kml file! In general, the normal way for a transformation would be... open the shape file it will open the "Coordinate Reference System Selector" select the coordinate systems (eg. EPSG 3309) and hit ...

The linked kml file seems to contain valid degree coordiantes, but fails to open in QGIS. If you follow the source given in your link to http://www.ecaidata.org/dataset/spanish-and-mexican-land-grants-in-california, you can get a shapefile which misses its prj file. With some kind of educated guess, you will find that NAD27 / California Albers EPSG:3309 ...

I'm not sure what you did and what went wrong, but: Openlayers plugin layers should be in EPSG:3857 Pseudo Mercator. This CRS is only useful for displaying web maps, and nothing else. WGS84 EPSG:4326 is a worldwide usable CRS using degrees as units. If you want to take measures (length, area, or angle), you should work with a CRS that minimizes ...
