@lucmar

I don't know. Not getting a apt.bak file

That should mean your apt.dat and apt.txt don't have the UTF8 BOM. My program is as lazy as myself: if there's nothing to do it does nothing

It only does something (and so creates the .bak) if the original file had a UTF8 BOM. But  if not it should tell you so: the message, IIRC, is something like: "That file doesn't need me: doesn't have a BOM."

I downloaded the apt.dat, will test it when (if!) I have a little time.

ETA: Oh, Thausand tested already. OK, then.

EATA

I not know program lucamar cleanbom but when have not BOM then why write file ? Then maybe program cleanbom read no BOM and then no write file new and no need file "apt.bak" ?

Yes, that's exactly how it works

[JLWest]

Here is where I'm at:

Went back and copied from:
C:\X-Plane 11\Resources\default scenery\default apt dat\Earth nav data\apt.dat
TO:
 c:\userfiles\apt.dat

Ran CleanBom

Ran MstAirports and generated a new byAirports.txt 34,680 records generated.

Ran Extractwordtext (Nice test) and tested the first record.

7 fields -everything OK

ran MstRegions and clicked on the first record which is always
[00C][28944][Nil][Nil][K2][37.203177778][-107.869194444]

Everything is Ok so I don't have a UTF8 BOM problem

Now to run down Thausand findings

[Thausand]

Hi hello JLWest,

I make new test (have fix 1 line miss error, was wrong count  ) and not can make same count like you program.

Alone when count airport ID 1, 16 and 17 then my program have almost same count you "ByAirport.txt". I have you "ByAirport.txt" size 2383401 and have ICAO 34680.

Then my program have many more ICAO  (have 35242)

I write list ICAO have my program and no have you "ByAirport.txt".

Then can see is no there normal ID "1" also in "ByAirport.txt" (have example EDUY) and also miss other ID airport "16" and "17". Then i think maybe error is in program you ?

Is 562 count list ICAO:

Maybe list have help find what wrong my or you program ?

[JLWest]

@Thausand

I'm working on it.

I think my number of 34,680 is pretty close.

X-Plane claims they have over 35,000 Airports.

I need the following info in ByAirports.txt:

All Land base airports.
All Sea plane bases.
Some Heliports (Those that are not located at an airport but like at a Hospital or on top of a building)

The ByAirports.txt file has 34,680 records. It is suppose to have one record for each airport in the apt.dat file with the following information:

[ICAO]    The ICAO airport code or location indicator is a four-letter code designating
              aerodromes around the world.

[Hash]   Hash number of the record location of the ICAO in Apt.dat.

[City]   City where the airport is located.  Might not have a city. Some airports are in the
           brush. Above the arctic circle, in the middle of no where, no city assigned.

[Country]   All airports as far as I can determine have a country.
[Region]    Should have a Region, However those without a Region are grandfathered in as
                valid data by X-Plane. Some are without Regions as far as X-Plane. The
                International Civil Aviation Organization has the rights to assigned all airports a
                region, but some don't have a region.

[Latitude]     All are suppose to have a Latitude of the airport. Some don't and you have to
                   use  either the Tower or runway center-line.

[Longitude] All are suppose to have a Longitude of the airport. Some don't and you have to
                 use  either the Tower or runway center-line.

Currently I'm showing in the ByAirports.txt  the following:

34,680 Airports
8,194 Cities,    I  think this is about 4 or 5 cities to many.
9,721 City,Region,ICAO  AbileneK4Kabi.


Unique record of City Region is not possible  (AbileneK4) as there is a Abilene K4 8T2S an Abilene K4 KABI, and a Abiline K4 KDYS. Many cities have more than 1 airport and they would all be in the same Region. 

I copied your list of 562.

You are missing ZYYY,ZYYJ 
[ZYYY][7105929][Shenyang][China][Nil][41.77619293][123.48947822] and quite a few more.

[Thausand]

Thanksy for more information JLWest.

X-Plane claims they have over 35,000 Airports.

Yes. have 35242 airport 

I need the following info in ByAirports.txt:
All Land base airports.
All Sea plane bases.

My program have make read from apt.dat and have any ID "1" and have any ID "16"

Some Heliports (Those that are not located at an airport but like at a Hospital or on top of a building)

My Airport.dat have count any heliport apt.dat. Have program check ID "17". My program not have 'remove'. I not know how decide remove. Specificate write Heliport unique and not combine land/sea port. Make sure i write my program not count helipads.

[City]   City where the airport is located.  Might not have a city. Some airports are in the brush. Above the arctic circle, in the middle of no where, no city assigned.

Yes, my program have same. Many no city name.

[Country]   All airports as far as I can determine have a country.

My program airport.dat write there have airport no ID 1302 or have ID 1302 and then no have item "country" then no have name country (=nil)

Have example ZMGT and have example ZMHG.

[Region]    Should have a Region, However those without a Region are grandfathered in as valid data by X-Plane. Some are without Regions as far as X-Plane. The International Civil Aviation Organization has the rights to assigned all airports a                 region, but some don't have a region.

Yes.  I can see my program to.

[Latitude]     All are suppose to have a Latitude of the airport. Some don't and you have to  use  either the Tower or runway center-line.

[Longitude] All are suppose to have a Longitude of the airport. Some don't and you have to  use  either the Tower or runway center-line.

This my program big error. I have many no lat/lon and if make then many different you ByAirport.txt. I try work my program make better. I have make read how read "runway center-line" because is have Airport many runway.

Unique record of City Region is not possible  (AbileneK4) as there is a Abilene K4 8T2S an Abilene K4 KABI, and a Abiline K4 KDYS. Many cities have more than 1 airport and they would all be in the same Region. 

Yes i have read. That is why my program flyby have error. If have London city England and have London city America. Now my program write is same "London" (i know is error my) and no unique city. I not have make hurry and make fix. I think is no many important now (maybe later is more important).

I copied your list of 562.

I make sure and write: List 562 is list ICAO that my program make and you ByAirports.txt file no have find.

You are missing ZYYY,ZYYJ

I'm trying to work with your programs but I'm not very good with DOS programs and can't make it work. Built a GUI test program but can't get it to compile.

Then have two option
1) make learn use dos 
2) make learn how write freepascal command program then write for Lazarus

Have 2 and can maybe me help you show.

I attach zip two. 1 is program flyby fpc command 2 is program flybylaz and make small terminal emulate. program 2 have many more lazarus part but no need for flyby program and is many same program (i have document and maybe can help you better understand how can make. Is not difficult copy-paste).

And i make attach picture for see.

If start program Lazarus then have make type "flyby name_of_airport.txt_file" (no quote) for edit then press button run for execute and if ok then show flyby write memo. If no ok then i hope print error for me read 

I hope maybe can help you little. If no then i sorry.

I have try, i no can make file attach to big. And then file me have many error (see paste this post many no have city, country and lat/lon). If want i can make ICAO list complete but is no magica. They all ICAO that have apt.dat. That why i write that you no have 562 ICAO and can look in program you why no find ?. I think that is logica. Is maybe possible i have make very wrong error. (i no admit and deny  ) 

If i have fix my program error lat/lon and city/country name then if good fix i post (maybe can split attach). If i diff you ByAirports.txt and me Airports.txt then diff too many and no usage compare

Lazarus project directory have 6 file:

Free pascal 'project' (is alone one file) directory have:

Code: [Select]

ls -l

-rw-r--r-- 1 pi pi 11528 May  6 01:53 flyby.pas

They separate project (one lazarus one fpc). Only have common that have source-lines that read exact same. That maybe can make show how can make project freepascal then make to project lazarus. Simple copy-paste 

Lazarus project make with Lazarus 2.0.0 release (use fpc 3.0.4) official and use publish project lazarus.

If some thing not work if load project lazarus then i not know why no work  .

When I click on flublaz.lpr I get the following message:

Is small suggest: maybe start lazarus and load project "flybylaz.lpi" ? (that is how i do)

"flybylaz.lpr(10,10) Fatal: Cannot find flyby_main used by flybylaz of the Project Inspector."

That is problem and big error. flyby_main is project main form (have form, panel, memo, button and edit).

Error: Can't open resource file "C:\Users\Jerry\AppData\Local\Temp\Temp1_flybylaz_publish.zip\flybylaz_publish\flyby_main.lfm"

As write more before. Not load project main form is error and problem. I not know why. What is version/platform  you Lazarus ? (i know you have tag-line but is not always use same lazarus and tag some time expire)

I have it running but I don't know how or why.

I not know to. If have error write above then in theory impossible ... maybe you wizard ? 

I get  "E:\Files\Airports\ByAirport.txt : command not found"

If run project then have main form open then make edit in editbox "flyby E:\Files\Airports\ByAirport.txt" (no quote) then push button that next editbox (is to right).

"command not found" mean you not have type flyby before 

Do I need to do this in a DOS Box you know CMD Line

lazarus project is run windows/desktop. That why i write because you write not know terminal. Now can have windows run small simulate terminal

"command not found" mean you not have type flyby before

Yes: I typed : E:\Files\Airports\ByAirport.txt and pushed the execute button.

I copied the ByAirports.txt file to the directory where the flyfy is and get the same results.

Looking at the code your suggesting that I copy part of the code out to a GUI New windows program and it.

That will take me a bit of time.

Yes: I typed : E:\Files\Airports\ByAirport.txt and pushed the execute button.

And is wrong 

Look picture: i type many wrong purpose for see. In picture final is good

Code: [Select]

flyby E:\Files\Airports\ByAirport.txt
And press button.

i write important: see "ByAirport.txt" is not have "s" letter and you copy have name "s" letter "ByAirports.txt" ?

I write many wrong english and not write all word and can maybe understand my write. Computer not so very smart and no understand if name no have match. If no have letter then not can find.

I copied the ByAirports.txt file to the directory where the flyfy is and get the same results.

if copy same directory "ByAirports.txt" then can type editbox:

Code: [Select]

flyby ByAirports.txt


Looking at the code your suggesting that I copy part of the code out to a GUI New windows program and it.

Yes. My program show and comment how can do.

That will take me a bit of time.

For now not you have do (i have make for you in zip)  .

Is alone show you how can do.

You no like terminal (is ok) and i no like Lazarus (for me is slow, have many bug and i many fight code-tool). I like more work terminal have vim, can make remote many and fast. Have example browse if use desktop browse then many MB/GB take website memory and in terminal have many website and more small 50-100 MB take memory for any.

Have other example "apt.dat" have 250 MB then doublecommand (or any) open and take more 5 minute for edit and then can look. Use terminal can make fast look (is make < 5 second):

Code: [Select]

Yea I think there is something wrong with the data.

Not sure how to fix it.

@Thausand

Attached 3 Screen Shots.

1. Listing of dir where your program along with byAirports.txt
2. What I entered.
3. Error Message.
In procedure RunCommandLine it goes from Line 13 to 23 no matter what I enter.

I can't figure out what the line is doing.

Code: Pascal  [Select][+][-]

1. procedure TTermiForm.RunCommandLine(CommandLine: string);
2. var
3.   index : SizeInt;
4.   s : string;
5. begin
6.   // have command print
7.   PrintLine(' $ ' + CommandLine);
8.   ParameterList := nil;
9.   ParameterList := CommandLine.Split([' ',#8,#9,#10,#13], '"');
10.   if Length(ParameterList) > 0 then
11.   begin
12.     // have command find in list
13.     index := CommandList.IndexOf(ParameterList[0]);
14.     // is find ?
15.     if (index >= 0) then
16.     begin
17.       // have execute command
18.       TProcedure(CommandList.Objects[index])();
19.     end
20.     else PrintLine(ParameterList[0] + ' : command not found');
21.   end
22.   else PrintLine('Empty command');
23. end;

I can't figure out what the line is doing.

This line?

Code: Pascal  [Select][+][-]

1. index := CommandList.IndexOf(ParameterList[0]);

It tries to find in CommandList (some kind of TStrings?) the string in ParameterList[0]. The if following it checks if it has found it and, if so, apparently executes a procedure whose pointer was saved in the "object" part of the string in CommandList.

I would have to see more code to explain better.
