开源软件名称(OpenSource Name):calvinmetcalf/shapefile-js开源软件地址(OpenSource Url):https://github.com/calvinmetcalf/shapefile-js开源编程语言(OpenSource Language):JavaScript 97.2%开源软件介绍(OpenSource Introduction):Shapefile.jsIf you are having encoding issues in internet explorer please include this script as well. Redoing all of this in modern JS. Promises, Typed Arrays, other hipster things, I wouldn't say it's based on RandomEtc's version as much as inspired by it as there is 0 code shared and I really only read the binary ajax part of his (hence why my function has the same name, they are otherwise not related). My sources were: DemosUsageFor use with browserify, webpack:
Or include directly in your webpage from:
APIHas a function //for the shapefiles in the folder called 'files' with the name pandr.shp
shp("files/pandr").then(function(geojson){
//do something with your geojson
}); or you can call it on a .zip file which contains the shapefile //for the shapefiles in the files folder called pandr.shp
shp("files/pandr.zip").then(function(geojson){
//see bellow for whats here this internally call shp.parseZip()
}); or if you got the zip some other way (like the File API) then with the arrayBuffer you can call const geojson = await shp(buffer); If there is only one shp in the zipefile it returns geojson, if there are multiple then it will be an array. All of the geojson objects have an extra key You could also load the arraybuffers seperately: shp.combine([shp.parseShp(shpBuffer, /*optional prj str*/),shp.parseDbf(dbfBuffer)]); Stick it in a workerI used my library catiline to parallelize the demos to do so I changed <script src='dist/shp.js'> </script>
<script>
shp('files/shapeFile.zip').then(function(data){
//do stuff with data
});
</script> to <script src='website/catiline.js'> </script>
<script>
var worker = cw(function(base,cb){
importScripts('dist/shp.js');
shp(base).then(cb);
});
//worker can be called multiple times
worker.data(cw.makeUrl('files/shapeFile.zip')).then(function(data){
//do stuff with data
});
</script> to send the worker a buffer from the file api you'd do (I'm omitting where you include the catiline script) var worker = cw(function(data){
importScripts('../dist/shp.js');
return shp.parseZip(data);
});
worker.data(reader.result,[reader.result]).then(function(data){
//do stuff with data
