UtmToALMaSS: Convert UTM coordinates to ALMaSS map coordinates

In LDalby/ralmass: Functions to Prepare and Analyze Data for and from ALMaSS

Description

Convert UTM coordinates into coordinates that can be used in in ALMaSS directly (also works the other way around). Useful when importing field data into ALMaSS

Usage

UtmToALMaSS(data, long, lat, map, subset = TRUE, toalmass = TRUE)

Arguments

data	data.frame The data frame with the coordinates
long	character The name of the column holding the longitude
lat	character The name of the column holding the latitude
map	character The name of the map used in ALMaSS
subset	logical Should the output only contain locations within the ALMaSS map? Ignored when toalmass = FALSE
toalmass	logical Do you want to convert to ALMaSS coordinates. Use FALSE if if you want to convert ALMaSS map coordinates back to UTM

Details

For Vejlerne there are currently two working maps: VejlerneTest (10000*7000) and VejlerneBigMap (36000*24000).

Value

data.frame A data.frame with the ALMaSS coordinates
