i would like to make the best mapping serices for clients for exact mapping layers for High tide line and low tide line ( which the data is being collected physically in x,y format) with this data should i make maps in arcmap10 with desired layers and desired scale for presenting the sylish maps.

if yes kindly be send each step by step procedure

you mention real-time? So you have real-time monitoring data of the tides that your trying to feed into your maps? What is the output format? Something online that is continuously updated or a static format? –  Simon Sep 9 '10 at 12:58

For what country?

Has this not already been mapped before for your region?

Do you have an accurate coastline outline for your region?
- How was this coastline derived?

You mention it is being surveyed with XY locations of each LWM/HWM - Would really need to get more info around this data collection before giving you a good answer.

A crude approach which is just me thinking off the top of my head.
I will try and put some more thought into this tomm when I have more time.

  • first get this XY data into ArcGIS and get it plotted out.
  • Get a DTM for the region. Ideally a DTM with good bathymetric heights as well.
  • Using Spatial Analyst create an interpolation of the XYZ data (Z being the attribute of either the HWM or the LWM). Perhaps use the inner coastline polygon layer as a barrier (?) I would 1st sugggest doing an Inverse Distance Weighted interpolation, setting the max distance based on how far your points are apart.
  • Using the grid calculator, subtract the DTM with the interpolated layer you created above.
  • Remove any negative values from the result.
  • This should give you a layer with the perimeter being the LWM/HWM depending on which results you interpolated above. You could then create a polygon extent of this grid and this would be your result.

I imagine this won't be the best answer (not in its current state) but perhaps it will cause others to suggest a better, more accurate answer. Or the author to give more info...

TBH, at the mo, I am reluctant to put more effort/time in until the question is phrased better.

Temporal Mapping Services are covered on the ESRI Website

http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/A_quick_tour_of_temporal_data_management_and_visualization/005z00000021000000/

Important that you understand the TIME construction - Use ROWS rather than columns etc.

http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Best_practices_for_storing_temporal_data/005z00000005000000/

This can be applied to ArcServer10 for Temporal Web Services.
