Questions in topic: "reader writer coordinate selection" https://knowledge.亚搏在线safe.com/questions/topics/single/62410.html网站 The latest questions for the topic "reader writer coordinate selection" Why is the geotiff reader not picking up the location? https://knowledge.亚搏在线safe.com/questions/85522/why-is-the-geotiff-reader-not-picking-up-the-locat.html

我有一个geotiff(sentinel-1 sar),可以在Arcgis中正确查看。在Arcgis属性中显示为gcs_wgs_1984。如果我在FME中读到它,然后写信给另一个TIFF,也可以。但是在FME中,它似乎丢失了地理内容,并切换到坐标系:未知,并且在检查器中显示的像素值好像是地理坐标。This means that I cannot perform any geographic operations on it (I plan to use rasterextentcoecer and mapnik).

这是我的读者的问题吗?或者我可以重新引入位置吗?The tiff has no world file so I dont actually understand where the georeferencing is stored - but arcgis can read it.

Correctly reading GeoPDF Coordinate System https://knowledge.亚搏在线safe.com/questions/69237/correctly-reading-geopdf-coordinate-system.html网站

我有一个地理空间PDF,其中包含许多层,我正试图将这些层导出到形状文件中。问题是生成的形状文件系统性地将项目放错了位置,所以我想象我一定不了解读者是如何阅读坐标系的。地质测向的来源是Canvas X GIS,可以直接导出到形状文件,expect that some of the information such as text objects are lost.I export the data into both shapefiles and the GeoPDF in NAD27 UTM 11N.When FME reads the GeoPDF,it assigns the coordinates asEPSG26711,这似乎是正确的。I also tried manually assigning it asUTM27-11,although that seem to place the objects in the same place after running the workbench.However when I first read the layers,然后查看数据检查器中的项目,它似乎没有指定地理坐标。I think that it only did so after I ran the workbench.在日志中,它谈论的是运行'LL-WGS84' -> 'UTM27-11.I do not understand why it would need to do so as my data should not be in WGS84.有人知道为什么FME会把我的数据放错地方吗?

以下是我添加另一个读卡器时获得的一些日志信息(要读取相同的层并将坐标系设置为epsg26711):

预先定义的坐标系统“UTM27-11”(带NAD27基准的UTM,11区,Meter;中央子午线117d w)匹配数据集坐标系

FME坐标系统“UTM27-11”的OGC定义为“ProJCS[“未命名”,GEOGCS[“Nad27”,基准[“D U北美U 1927”,球体[“Clarke U 1866”,6378206.4294.97869821339,权威[“epsg”,“7008”]],权威[“epsg”,“6267”]],素数[“格林威治”,0,权威[“epsg”,“8901”]],基准转换[2,2],单位[“度”,0.0174532925199433”,权威[“度”,单位[“度”,0.01745327453292519943433”,权威[“度”,权威[“度”,单位[“度”,[2,2,EPSG,“4267”]],投影[“横轴墨卡托”]、参数[“东移误差”,500000]、参数[“北移误差”,0]、参数[“比例因子”,0.9996]、参数[“中轴子午线”,-117]、参数[“原点纬度”,0],单位[“米”,1]]'

FMEConfiguration: Using FME Reprojection Engine

cs-mapreprojector:转换将自动选择为'll-wgs84'->'utm27-11',and is not guaranteed to remain the same in future releases of FME

Reprojector:Using transformation `NAD83_to_WGS84,Inverse(Null,EPSG:1188)' when reprojectingfrom LL-WGS84 to UTM27-11

重投影:从ll-wgs84重投影到utm27-11时,使用转换“nad27_to_nad83,inverse(grid fileinterpolation,epsg:1241)”。

当我运行工作台时,它给出了这个结果:

预先定义的坐标系统“UTM27-11”(带NAD27基准的UTM,11区,Meter;中央子午线117d w)匹配数据集坐标系

FME坐标系统“UTM27-11”的OGC定义为“ProJCS[“未命名”,GEOGCS[“Nad27”,基准[“D U北美U 1927”,球体[“Clarke U 1866”,6378206.4294.97869821339,权威[“epsg”,“7008”]],权威[“epsg”,“6267”]],素数[“格林威治”,0,权威[“epsg”,“8901”]],基准转换[2,2],单位[“度”,0.0174532925199433”,权威[“度”,单位[“度”,0.01745327453292519943433”,权威[“度”,权威[“度”,单位[“度”,[2,2,EPSG,“4267”]],投影[“横轴墨卡托”]、参数[“东移误差”,500000]、参数[“北移误差”,0]、参数[“比例因子”,0.9996]、参数[“中轴子午线”,-117]、参数[“原点纬度”,0],单位[“米”,1]]'

FMEConfiguration: Using FME Reprojection Engine

cs-mapreprojector:转换将自动选择为'll-wgs84'->'utm27-11',and is not guaranteed to remain the same in future releases of FME

Reprojector:Using transformation `NAD83_to_WGS84,Inverse(Null,EPSG:1188)' when reprojectingfrom LL-WGS84 to UTM27-11

重投影:从ll-wgs84重投影到utm27-11时,使用转换“nad27_to_nad83,inverse(grid fileinterpolation,epsg:1241)”。

reprojector:'nad27_to_nad83,inverse(gridfile interpolation,epsg:1241)'将使用以下网格移位文件:

reprojector:c:\program files\fme\reproject\griddata\nadcon\conus.l?S

reprojector:c:\program files\fme\reproject\griddata\nadcon\alaska.l?S

Reprojector:C:\Program Files\FME\Reproject\GridData\Nadcon\prvi.l?s

Reprojector:C:\Program Files\FME\Reproject\GridData\Nadcon\stlrnc.l?s

Reprojector:C:\Program Files\FME\Reproject\GridData\Nadcon\stpaul.l?s

再投影:如果一个点超出“nad27-48”到“nad83”的可用范围,则将使用以下回退变换:“nad27-48”到“wgs84,反向(多重回归)”。

不将关键字“pdf2d_1”标识的读卡器坐标系从“epsg:26711”更改为“utm27-11”--映射文件设置“epsg:26711”替代坐标系“utm27-11”从文件读取

And when I run the workbench and reset the reader coordinate system toUTM27—11,it gives me slightly different results:

Predefined coordinate system `UTM27-11' (UTM with NAD27 datum,11区,Meter;Central Meridian 117d W) matches dataset coordinate system

重新投影:从ll-wgs84重新投影到utm27-11时,使用转换“nad27_to_nad83,inverse(网格文件插值,epsg:1241)”。

reprojector:'nad27_to_nad83,inverse(网格文件插值,epsg:1241)'将使用以下网格移位文件:

Reprojector: If a point is outside the usable range of 'NAD27_to_NAD83' the following fallback transformation will be used: 'NAD27-48_to_WGS84,Inverse(Multiple Regression)'
