A CLI utility written in Go to validate and parse ESRI ASCII raster data file to various devices (i.e., console, file, database).
An example of the how the output of this parser can be used is noted here, as a population density plot in Google Maps:
For specific file format details, see the ESRI ASCII raster data format specification reference.
- Go language distribution
- Supplemental Go packages:
- Go-SQL-Driver package (http://github.com/go-sql-driver/mysql)
- Operational database (if persisting to a database,
dev=db)- See MySQL DDL project sample (test_world_create.sql)
While this package was written and tested under Linux (Ubuntu 14.04 LTS), there should be no reason why this won't work under other operating systems.
To meet the Go-SQL-Driver package dependency, install the package into your Go environment ($GOPATH) using the go command tool:
$ /go/src$ go get github.com/github.com/go-sql-driver/mysql
Similarly, install this esri-ascii-parser package into the Go environment:
$ /go/src$ go get github.com/richbl/esri-ascii-parser
Both package sources should be viewable under the $GOPATH/src folder (e.g., /go/src/github.com/richbl/esri-ascii-parser).
Esri-ASCII-Parser is run through a command-line interface (CLI), so all of the command options are made available there.
Here's the default response when running esri-ascii-parser with no parameters:
$ esri-ascii-parser
--------------------------------------------------------------------------------
esri-ascii-parser: ESRI ASCII raster data file parser (v0.10)
validate and parse file to console, file, or database
--------------------------------------------------------------------------------
-in must be set to a fully qualified pathname for input
Current settings:
-in=
-out=/tmp/file.out
-dev=con
-db=
-name=region
Usage:
esri-ascii-parser (-in="</path/to/esri_file>") [-out="</path/to/file.out">]
[-dev=<"con">, <"file">, <"db">]
[-db="[username[:password]@][protocol[(address)]]/dbname"]
[-name=<"region">]
Options:
-db="": database to persist parsed results (used when -dev=db)
-dev="con": output device(s): con, file, db, e.g,. -dev=con,file
-in="": fully qualified pathname of esri ascii raster file to parse (required)
-name="region": name to uniquely identify a region (used when -dev=db)
-out="/tmp/file.out": file to persist parsed results (used when -dev=file)
Examples:
esri-ascii-parser -in=/abc.asc
esri-ascii-parser -in=/abc.asc -dev=con,file
esri-ascii-parser -in=/abc.asc -dev=file -out=/tmp/results.out
esri-ascii-parser -in=/abc.asc -dev=db -db=usr:pwd@tcp(10.10.10.1:3306)/db
In this example, the utility responds by indicating that the -in parameter must be set to an input file to be parsed (otherwise, what's the point if the input file is null, really).
The output generated from the parse of the utility is managed with the -dev parameter. By default, it's set to console (i.e., -dev=con), but it can be set to multiple devices at once (e.g., -dev=con,file). Note that depending on how this parameter is set, additional parameters will need to be set.
