MAPFST(3NCARG)

✨ MAPFST — the NCAR Graphics girlies know 💅

okay so bestie, we're in NCAR GRAPHICS land and this page is literally about MAPFST, a Fortran (and C!) routine that draws lines on a map. It only really makes sense next to its partner in crime, MAPVEC. 🗺️✨

---

🌸 NAME 🌸

MAPFST — draws lines on a map, and it's meant to be used in conjunction with MAPVEC. no cap.

---

🎀 SYNOPSIS 🎀

CALL MAPFST (RLAT,RLON)

---

💖 C-BINDING SYNOPSIS 💖

#include <ncarg/ncargC.h>

void c_mapfst (float rlat, float rlon)

---

🦋 DESCRIPTION 🦋

• RLAT and RLON — these are input expressions, of type REAL, and they say where the "pen" is getting moved to. Think of it like telling your little cursor bestie where to go next. 🖊️

Both of them are given in degrees, okay? Important.

• RLAT must be between -90. and +90., inclusive. (it's giving latitude, so like, yeah, that tracks 💀)
• RLON must be between -540. and +540., inclusive. yes, five hundred and forty. she's flexible like that. 🌈

---

🌟 C-BINDING DESCRIPTION 🌟

The C-binding argument descriptions are the same as the FORTRAN argument descriptions. same vibe, different syntax, slay. 💅

---

🔥 USAGE 🔥

okay so this statement:

CALL MAPFST (RLAT, RLON)

is equivalent to this statement:

CALL MAPIT (RLAT, RLON, 0)

What it does: it moves the "pen" (which is in the "up" position, so it's not drawing yet, she's just traveling ✈️) to the first point in a series of points.

fr fr, go read the man page for MAPIT if you wanna know more — MAPFST is lowkey just MAPIT with extra steps. 👑

---

👑 ACCESS 👑

To use MAPFST or c_mapfst, you gotta load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c — and preferably in that order, bestie. don't fight the order, she knows what she's doing. 🫶
