    Hi , this is a very quality image. where can i find one like this for my catchment? i tried landsat (earthwxplor USGS) but they are not as quality as this is.

    Which composite band is convenient for landsat 5 to extract river shape?

    Hi! Good morning! I am Myrnalyn from the PHILIPPINES a BS in Geodetic Engineering student! I've been viewing the video you posted on facebook and i even subscribed you because the videos you uploaded were really helpful for my thesis since I have an ongoing thesis now entitled "USING LANDSAT-DERIVED DATA AND NDWI FOR THE ASSESSMENT OF COASTLINE CHANGE IN SURIGAO DEL SUR, PHILIPPINES.
    1. I have alot of queries now, especially that I have found that I can extract shorelines without using NDWI. What the best thing or way to extract shoreline? I'm using the LANDSAT DATA for the year 1997, 2001 and 2015..
    2. Can i ask a suggestion from you what's the best thing or way to do to extract and detect changes of the coastline in an easy way since I only have 1 more week to do this ..
    I hope I could get a response from you, Sir!

    Hello, i have a similar task at hand, however my file (jpeg) wont open. Does it need to be converted to another format? Would really appreciate a response. Thanks!

    • @Geologyfieldtrip

      Tanvi Gurjar , jpeg file is not good to extract the features from image. And it also has not geo reference. You should use original image with geo reference

    hello~ I have some question can you do me a favor. What's your image resolution and how to find a flood plan. Do you change original image color? If you have and how to change? Thanks:)

    • @Geologyfieldtrip
      @Geologyfieldtrip  6 лет назад

      yes, i have,
      you can do it if your image download with many band(Landsat8). then combine them as false color, you will see the contrast between land, water and forest

    Hello. I did not understand the step 5. How to edit polygon and copy the river body to other shape and save. Please explain it in detail. Thank you Mr.

    • @Geologyfieldtrip
      @Geologyfieldtrip  6 лет назад

      Step 5, is final step to clear not important features for your product, so we to edit and delete the feature are not important. Before select we must go to edit feature first, as in this video I select one river as my product and switch select to select any feature then I delete.

    I followed all the steps but it was failed when I converted the image to the polygon, do you have any advice?

    • @Geologyfieldtrip
      @Geologyfieldtrip  6 лет назад

      ensure that you use the raster image, Raster image that done on Reclassification step.

    • @lifecharger101
