GetCoverage

请求

请求参数

参数名称	是否必填	描述
service	是	服务名示例：WCS
request	是	请求名示例：GetCoverage
version	否	版本示例：2.0.1
coverageId	是	指定所要请求的图层，从GetCapabilities返回的XML信息的CoverageId节点中获取。
mediaType	否	同时需要XML和图像输出时，应该设置为' multipart/related '(这是该参数目前唯一可能的值)，IGServer暂不支持该参数。
format	否	返回的格式，从GetCapabilities返回的XML信息的formatSupported节点中获取。示例：format=image/tiff
subset	否	允许使用给定的范围来获取数据，参数包含轴类型(宽高)和给定轴的范围信息(宽高的范围区间)，每个轴唯一。示例：subset=Long(0,10)&subset=Lat(0,10)，Long表示宽，Lat表示高。
subsettingCrs	否	范围参照系，传入的subset范围信息必须是该参照系下的范围。示例：subsettingCrs=EPSG:4326
outputCrs	否	输出参照系，数据的参照系通过此参数设置，如果数据本身参照系与输出参照系不同，会返回投影后的数据。示例：outputCrs=EPSG:4326
scaleFactor	否	使用这个参数(一个正浮点数)可以调整输出图像的大小，图像的宽高等比例放大或缩小示例：scaleFactor=1.5
scaleAxes	否	指定轴类型(宽高)进行放大或缩小。示例：scaleAxes=Long(2)&scaleAxes=Lat(3)，Long表示宽，Lat表示高。
scaleSize	否	指定轴类型(宽高)的像素大小。示例：scaleSize=Long(100)&scaleSize=Lat(100)，Long表示宽，Lat表示高。
interpolation	否	重新缩放图像的插值方法。从GetCapabilities返回的XML信息的interpolationSupported节点中获取。示例：interpolation=http://www.opengis.net/def/interpolation/OGC/1/nearest-neighbor
rangeSubset	否	选择波段,从DescribeCoverage返回的XML信息的field节点中获取。示例:rangeSubset=band1(单波段)或者rangeSubset=band3,band2,band1(多波段)
geotiff:comperssion	否	压缩方式。示例：geotiff:comperssion=Jepg或者LZW
geotiff:jpeg_quality	否	Jpeg压缩质量。示例：geotiff:jpeg_quality=100

请求示例

http

{{server}}/igs/rest/services/:serviceName/WCSServer?version=2.0.1&request=GetCoverage&service=wcs&coverageId=world__world&format=image/png

响应

结果根据传入的格式返回图片、tiff数据、text文本

示例

1.默认请求(返回全图)

{{server}}/igs/rest/services/:serviceName/WCSServer?version=2.0.1&request=GetCoverage&service=wcs&coverageId=world__world&format=image/png

2.根据范围请求

{{server}}/igs/rest/services/:serviceName/WCSServer?version=2.0.1&request=GetCoverage&service=wcs&coverageId=world__world&format=image/png&subset=Long(-10,10)&subset=Lat(-10,10)

3.指定宽高

{{server}}/igs/rest/services/:serviceName/WCSServer?version=2.0.1&request=GetCoverage&service=wcs&coverageId=world__world&format=image/png&subset=Long(-10,10)&subset=Lat(-10,10)&scaleSize=Long(100)&scaleSize=Lat(100)

4.缩放返回的图片
