Been done that few weeks ago, and it is still working

You are welcome

You are welcome

No, how would I know? I never see your data

It is just simply choosing an elevation value based on your preference

Ada, banyak, tapi kebanyakan berbayar , versi free nya dibatasi 100 records biasanya, misalnya mapcite

@@GEO2004 siap... makasih mas

You can build raster attribute table from geoprocessing tool,

@@GEO2004 Good morning! I tried your suggested step on geoprocessing tool in ArcGIS Pro but it fails to build attribute table. Do you have any suggestions or alternative solution for this?

I don't, there can be many error sources, without looking the data myself, I can't be sure, guess you can keep trying and watch closely my video, and figure it out what is the difference between my data and yours, and go from there

I have using it few weeks ago and still working,

Di geoportal tanah air indonesia, googling aja

There are few ways, 1. Use a DSM, you can get them from your country government mapping agency. DSM can also generated photogrammetrically from UAV based survey. 2. Satellite imagery (not like google satellite image, but true satellite imagery you have purchased from its vendor/publisher), you can get the height information like I described in this video : czcams.com/video/dBwaBNorJns/video.html

Add other data in same area that have correct world map information, if those data overlaid correctly, then they must be correcy

Datanya google maps? Secara langsung Ga bisa, karena closed source, Kalau pakai pendekatan routing bisa, tapi harus pakai layanan google routing API dan harus aktifkan billing di google cloud platform pake kartu kredit, nanti per hari bisa dapat 2500 free API calls kalau ga salah,lebih dari itu bayar kena billing. Itu baru satu hal, berikutnya, harus bikin kode di python untuk melalukan routing secara iteratif berdasarkan titik koordinat origin - destination yang anda juga harus pikirkan sendiri bagaimana cara membuatnya, Nampak rumit? Memang! Apakah ada alternatif data lain, ada, openstreetmap, tapi tentu datanya tidak selengkap google.

@@GEO2004 oh berarti tidak bebas bayar ya pak. Utk di osm saya sdh cek namun di daerah yg saya akan teliti hanya sedikit yg ada keterangan apakah jalan x satu arah atau tidak. Saya kepikiran utk digitasi manual mengikuti arah tapi krn butuh data level kota jd blm saya lakukan

Ini kepentingannya untuk network analysis? Kalau iya,ga usah sampai digit lagi, tinggal set up kode arah di atribut saja trus input kode arah per ruas jalan.

@@GEO2004 betul pak utk network analysis. Berarti tahapannya: unsuh data dr osm - tambah field baru - identifikasi jalan apakah oneway/tdk. Utk data jalan yg satu arah dr osm didigitasi sesuai dengan kemana arah jalan tsb menuju ya pak?

Untuk arah tinggal bikin field lgi

Yeah you can

@@GEO2004 can you please make a video on that

I have done that, kindly check the other videos in my channel

You must install snaphu, there is no other solution

@@GEO2004 Thank you, I installed the unwrap plugin, I was able to use the unwrap tool.

Just use slope tool from 3d analyst and use DEM as input, if your data still in contour line, generate DEM from it using topo ro raster tool

It is because the zoom scale limitation of the basemap, you can do nothing about it

Sure, you can use any DEM, just make sure you change any calculation that involves DEM resolution

What do you mean? Explain more completely please

​@@GEO2004 at 1:54 I see you have 6 options, but I only have 2. I wonder maybe my account doesn't have those function

You need to have arcgis online organizational account for this to work, my guess your account might be arcgis online public account, you can apply for trial to get organizational account.

Macam macam

Inspect in the imagery between cloud cover area and no cloud area

I think it is not, however, I am not sure

How long is your calculation?

I am sorry, kind of forgot

No, it is not.

Simplenya, coba dimainkan ukuran binnya,

You can try majority filter from spatial analyst tool for them, expect some data loss

Yeah, you can also use reclassify

Kemungkinan proses unwrapnya tidak benar atau inteferogramnya sangat jelek sehingga unwrapnya tidak berhasil. Interferogram jelek ditandai dengan tidak adanya pola pola fringe yg unik dan hasil inteferogram jelek lebih kayak random warna pixelnya seperti siaran tv yg tidak daapt sinyal, layarnya cuma kayak semut2 bertebaran hehe

Betul, interferogram yg saya hasilkan, tidak seperti warna pelangi di video, namun lebih seperti siaran tv rusak. Apakah ada solusinya untuk itu? 🥹🙏​@@GEO2004

@@GEO2004 iya memang betul interferogramnya tidak seperti pelangi seperti di video, namun seperti tv tidak ada sinyal, jika interferogram nya jelek apakah ada solusinya? Terimakasih..

Tidak ada solusi, karena selisih waktu perekaman antar citra cukup lama, apalagi kalau penutup lahannya banyak vegetasi, kalau mau lebih baik hasilnya, cari lokasi yang tidak ada/minim vegetasi

No, the georeferencing is included when I do the ground control points input, About the orthomosaic greyed out, have you set the output map projection from references pane? Maybe that is the culprit.

@@GEO2004 Thanks for your reply. I didn't set output map projection, but I did now and that doesn't change anything... Any other ideas?

You must repeat all the process from the start,only this time set the map projection before doing alignment

Ya tidak, emang citra apa yang band nya 11 ? Kalau sentinel 2 atau landsat 9 kan tidak semua band dipakai.

Dunno, I don't use macbook anymore

Did you really know the ground coordinates of the fiducial points? If you are not, that is the problem, if you only have the fiducial coordinates in pixels and in milimeters based on printed aerial photographs dimension, you better doing it in dedicated metric photogrammetry software such as ENVI, erdas imagine ortho maker, pci geomatica ortho engine, or BAE Socet Set.

It will changed, yes, there will be inconsistencies in ndvi values

Yes, you still need to perform those atmospheric correction/boa reflectance, unless you are using L2 or L3 data, you don't have to do it.

@@GEO2004 Thank You so much. Can you please tell me how to convert it to BOA or relectance?

all right, I will make a video about it

@@GEO2004 Thank you... Just to confirm ... DO I need to convert L1T to TOA/BOA after I have done pre processing (radiometric/Atmospheric) ?

Seems you are not understand, if you do atmospheric correction, you are exactly got BOA reflectance

Citranya warna apa hitam putih? Soalnya itu errornya karena citranya ndak rgb 3 warna

warna mas citranya, itu saya pake foto udara RGB

Kemungkinan karena format ecw nya sih, coba pake formst geotif aja

The pdf creation with mentioned features is easy, however, not all pdf reader has the ability to show and read the hyperlink

@@GEO2004 please make tutorial

I will consider it

Usgs have some extensive spectral library, however the format is not easily implemented in most software, ENVI also have some spectral libs which can you use

cds.climate.copernicus.eu/cdsapp#!/dataset/satellite-soil-moisture?tab=overview, this data is good, the resolution is very coarse tho

I think qgis can't do it yet,

@@GEO2004 ah i see thanks

Probably, I kind of forgot the sequences,

@@GEO2004 Have you also tried ionospheric correction here for ALOS strip map? the low band (by Bandpass Filter) seems kinda weird here

Have tried it for sentinel 1. I don't see noticeable difference,

Yes, you must export the data to geotiff format tho

@@GEO2004 and that's because ESA exports the product as a .jpg and not a .tif like the USGS does, right?

@@nomadhomad3685 yes

this might be due to the interferogram quality is bad, so unwrapping found some unresolved calculation

@@GEO2004 Thanks

There are plenty of way to do it, NDWI is one of the best approach.

Free with default features, yes you can with some additional javascript code
