As hinted by "feeling around in the dark", Braille can be used to decode the first of the 11 squares by dividing the grid into 2x3 segments and reading the white squares as the pips.
This decodes to the message START_HERE_COMBINE_THESE. This is a hint to combine the grids together. The exact method is hinted by "Inexorable" and "logically combined" which is a clue to use an XOR Logic Gate.
XOR Logic Gate
Combining the first grid with the second grid (combining the pixels in the same location) gives a new output.
This new grid can again be read via Braille but this time using the black squares as the pips.
XOR with Grid 2: BALANCE_BY_MARCIA_BILLIG
This one gives the message BALANCE_BY_MARCIA_BILLIG. Each new grid can again be XORed with the grid following it to give a new grid with a new Braille message (alternate between black and white pips on each grid) to give 10 grids total giving a message with a location.
XOR with Grid 3: THE_BAYSIDE_BANYAN_TREE
XOR with Grid 4: CHUNKING_MANSIONS_FRONT
XOR with Grid 5: FLAX_MURAL_BY_MASKAGRAM_
XOR with Grid 6: IRVING_IN_PROSPECT_PARK_
XOR with Grid 7: THE_ISHINKI_TOUCHSTONE_
XOR with Grid 8: MODERN_PASTRY_IN_THE_HUB
XOR with Grid 9: THE_OBELISK_OF_DISTANCES
XOR with Grid 10: ORBIS_HOTEL_BRACKA_GLOBE
XOR with Grid 11: WINGED_OX_ON_TJU_CAMPUS
