Example if a gene X is located on chromosome 2 in the region between 10000 bp and 16000 bp. I want to get this kind of information about the location of genes for all human genes. I guess the data is available online and it's just a matter of knowing how to access the data!
NCBI MapView allows you to locate genes between genomic co-ordinates on particular chromosomes but I'm not sure how you can do it for all the genes in the human genome
If you want to look up the locations of a few specific genes you can find it using the UCSC genome browser:
http://genome.ucsc.edu/cgi-bin/hgGateway
If you want to get lists of all genes and their location (as tab delimited text files for example) you can always try:
http://www.ncbi.nlm.nih.gov/refseq/
http://www.genenames.org/
There is a conceptual problem with the idea that a gene would have an absolute "chromosomal address" described quantitatively in base pairs. All human chromosomes carry variable number tandem repeats (or VNTRs) that occur with different numbers of repeats in different individuals. As a result, some human chromosomes show length variations of up to 10% across "normal" individuals. Given the size of human chromosomes, a possible 10% length variation means the bp address of a gene could vary by millions of base pairs across different individuals. It is better to represent gene locations using relative addressing, where the location is specified relative to some nearby genomic landmark.
