[MapProxy] MapProxy Seeding in a certain scale

[Andras Szekeres]

Hello,

I`m still wondering how to do it, so some more information:
When I do mapproxy-util grids --grid grid4258 --mapproxy-conf  mapproxy.yaml

I get:
 Levels: Resolutions, # x * y = total tiles
        00:  0.12448515433241368,    #      1 * 1      =        1
        01:  0.06224257716620684,    #      2 * 1      =        2
        02:  0.03112128858310342,    #      4 * 2      =        8
        03:  0.01556064429155171,    #      8 * 4      =       32
        04:  0.007780322145775855,   #     16 * 8      =      128
        05:  0.0038901610728879275,  #     32 * 16     =      512
        06:  0.0019450805364439638,  #     64 * 32     =   2.048K
        07:  0.0009725402682219819,  #    128 * 64     =   8.192K
        08:  0.00048627013411099094, #    256 * 128    =  32.768K
        09:  0.00024313506705549547, #    512 * 255    = 130.560K
        10:  0.00012156753352774773, #   1024 * 509    = 521.216K
        11:  6.078376676387387e-05,  #   2048 * 1017   =   2.083M
        12:  3.0391883381936934e-05, #   4096 * 2033   =   8.327M
        13:  1.5195941690968467e-05, #   8192 * 4066   =  33.309M
        14:  7.5979708454842334e-06, #  16384 * 8132   = 133.235M
        15:  3.7989854227421167e-06, #  32768 * 16263  = 532.906M
        16:  1.8994927113710584e-06, #  65536 * 32525  =   2.132G
        17:  9.497463556855292e-07,  # 131072 * 65049  =   8.526G
        18:  4.748731778427646e-07,  # 262144 * 130097 =  34.104G
        19:  2.374365889213823e-07,  # 524288 * 260193 = 136.416G

And for the scale:

res: [
    #  res            level     scale @90.7 DPI
      8.4000000000, #  0       30000.00000000
      5.6000000000, #  1       20000.00000000
     ]
As a grid I defined in my mapproxy.yaml:

grids:
 hungary_4258:
     srs: 'EPSG:4258'
     bbox: [15.996,45.652,22.939,48.647]
     bbox_srs: 'EPSG:4326'
     res: [
    #  res            level     scale @90.7 DPI
      8.4000000000, #  0       30000.00000000
      5.6000000000, #  1       20000.00000000
     ]

My seed.yaml:

seeds:
  seedjob:
    caches: [hungary_cache]
    grids: [epsg4258]
    coverages: [hungary]
    levels:
      to: 19

coverages:
  hungary:
    bbox: [15.996,45.652,22.939,48.647]
    bbox_srs: "EPSG:4326"

I don`t get the link between scale and level.From where do I know which level is which scale? Which level would be 1:20 000? 
Do you need more information to help me?
Thanks for your fast reply.

Greetings,

Andras
