Sir I'm getting error when I try to generate transect, it shows " Optional field not found in shoreline layer: shoreline. DATE "... In this case what should I do

@dawnofgeospatialworld Месяц назад
Have you created the DATE column in shorelines shapefile? if yes, then check the date format as mentioned and change your system's date format as MM/DD/YYYY format

Hello sir,the tide level data I can obtain is incomplete, if I fill in all the 0 in the uncertainty area, would it be a big impact?
@dawnofgeospatialworld
@dawnofgeospatialworld 3 месяца назад
Taking 0 as uncertainty will give you some little error to your result. You can keep it 1 to 1.5m

Sir, why have you put two dates in the column of Acquired Date in the Excel sheet? and my datasets belong to the month of January, February and March. how will i find the seasonal error for these dates?
@dawnofgeospatialworld
@dawnofgeospatialworld 5 месяцев назад
I have written two dates because this area is comes under 2 different dates and I have to mosaic 2 satellite images. But if your area comes under only one satellite image, then you can write only that acquired date. Mostly Winter season has 0 seasonal error. but if you take summer or rainy season or 2 different seasons, then seasonal error will change. So try to take winter season time satellite images it will also be cloud less.

Sir, when calculating statistics its showing error how to overcome this, ? And when label transects it showing 0 to all transects ,. How to label those correctly
@dawnofgeospatialworld
@dawnofgeospatialworld Месяц назад
Which error comes? for labeling go to properties of transects > Label > Select ID for labeling

sir, sorry to bother you again. I need to calculate LRR and NSM only in that case shall I only select LRR from the 'select statistics to calculate' box and then also LRR in the 'rate for colour ramp display'? Or are the LRR attribute values that I have while doing WLR like in the video enough? And if I want to calculate EPR do I have to create databases separately for two - to two years and perform the DSAS analysis?
@dawnofgeospatialworld
@dawnofgeospatialworld 5 месяцев назад
you can select your required parameter to calculate. But for displaying the rates on canvas you need to run separately. like one time for NSM & one time for LRR from colour ramp display.
@dawnofgeospatialworld
@dawnofgeospatialworld 5 месяцев назад
NSM, EPR & LRR are for short term change analysis. like 1 or 2 years gap while WLR is for long term analysis with many year's shoreline

Sir, should we not trace the inner boundary line as the baseline? since the land(coast) area is inward. why are we tracing outer boundary as the baseline? please tell sir 🙏
@dawnofgeospatialworld
@dawnofgeospatialworld 6 месяцев назад
We need to calculate the changes from continental shelf side. That's why we take outer boundary line

Sir what if I don't want to consider tidal effects, can I just skip the uncertainty calculation step then? Sorry if the question may seem stupid

Yes you can. Just keep in mind that how much tidal height can be appeared in your study area. Place that value in uncertainty parameter.
